opencv_contrib's Issues

Building OpenCV 3.0.0-beta contrib text sample application

I am trying to build the sample applications from opencv-3.0.0-beta with opencv_contrib-3.0.0-beta.

Here is what I have done

1. Downloaded and unzipped: https://github.com/Itseez/opencv/tree/3.0.0-beta to /home/me/opencv
2. Downloaded and unzipped https://github.com/Itseez/opencv_contrib/tree/3.0.0-beta to /home/me/opencv
3. mkdir /home/me/opencv/opencv-3.0.0-beta/build
4. cd /home/me/opencv/opencv-3.0.0-beta/build
5. cmake -DOPENCV_EXTRA_MODULES_PATH=/home/me/opencv/opencv_contrib-3.0.0-beta/modules /home/me/opencv/opencv-3.0.0-beta
6. make -j5
   The above works perfectly, no errors.

However I was expecting the sample applications to build, the only one I really care about is: /home/me/opencv/opencv_contrib-3.0.0-beta/modules/text/

I have tried building it with the following steps

1. cd /home/me/opencv/opencv_contrib-3.0.0-beta/modules/text/

2. sudo cmake .
   However I get an error, here is the output I get!

   -- Tesseract: NO CMake Error at CMakeLists.txt:21 (ocv_define_module): Unknown CMake command "ocv_define_module".

   CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present. A line of code such as

   cmake_minimum_required(VERSION 2.8)
   should be added at the top of the file. The version specified may be lower if you wish to support older CMake versions for this project. For more information run "cmake --help-policy CMP0000". This warning is for project developers. Use -Wno-dev to suppress it.

   -- Configuring incomplete, errors occurred!

Test this repository with Travis-CI

I want to try to test this repo using Travis-CI. I think it is possible, since right now we only several modules, so tests shouldn't take too much time.

Also, it will be tested on Ubuntu Linux only (but with GCC and Clang), but it is better than nothing (what we have right now).

Reference to non-existent field 'rootfilters'

Hi,

When I run the script on 'person_final.mat' of VOC2010 models as:

mat2xml('person_final.mat','person.xml')

it give me the error:
Reference to non-existent field 'rootfilters'.

Please help me solve this error. Thank you.

Hi there

thanks for the great work on opencv! I'm facing the following problem
Linking CXX shared library ../../lib/libopencv_xobjdetect.so

any ideas?

Issue deallocate: Ptr<OCRTesseract>

Hi,
like the title, in all two sample, the object Ptr present issue when program end: in memory deallocation phase.

My system configuration is:

• Win 8.1
• VS2013
• OpenCV 3 beta.

error is:
HEAP CORRUPTION DETECTED

I have not this error if declare static Ptr and run app in release mode.

Sorry for my English.
Nicola

I have attached screenshot error.

computeSaliency does not get correct results

i use BING as algorithm type to compute the boundingbox of an image, the sample project "computeSaliency" runs fine ,but the result is not ok, it gets too many boxes.

i painted the results on the source image ,like this

i compile opencv contrib with opencv 3.0, i wonder to know has anyone successfully run the example and get right results? what the problem may i meet?

Two issues in utils.cpp (datasets modul) when building with mingw-w64

Hi,

building with mingw-w64 leads to:

too many arguments to function int mkdir (const char*)

and:

alphasort was not declared in this scope

Possible solutions:

• First error

void createDirectory(const string &path)
{
#if defined __GNUC__ && !defined __MINGW32__
    mkdir(path.c_str(), S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH);
#else
    mkdir(path.c_str());
#endif
}

• Second error

void getDirList(const string &dirName, vector<string> &fileNames)
{
#if defined __GNUC__ && !defined __MINGW32__
...
#else // for WIN32
...

Sample from modules/reg/samples/map_test.cpp does not compile

Hi Kiril,

Sorry if i assigned the issue to you but the author Alfonso (alfonsosanchezbeato ) does not appear in the assignies list.

this sample does not compile.

First, you should change your includes referring to opencv modules
For example: replace

#include <opencv2/highgui/highgui.hpp>
by
#include <opencv2/highgui.hpp> // but note that teire are two similar lines including highgui

Here is the compiler errors i have with the original submission

The exception happens only when I build opencv with IPP option on. It succeeds when I build with IPP option off.

Building system on branch master fails, while 2.4 branch works

After trying to debug this for several hours, I ask for your help:

The cvv module builds fine against the opencv 2.4 branch.
After updating cvv for opencv master branch (see cvv_opencv_3.0.0 branch https://github.com/andreasBihlmaier/opencv_contrib/tree/cvv_opencv_3.0.0),
it compiles just fine against current master with an external CMakeLists.txt (https://github.com/CVVisualPSETeam/CVVisual/blob/master/CMakeLists.txt).
However, building it as extra module results in a totally broken libopencv_cvv.so [1], which manifests itself as a linker error for the cvv example [2]. I hope the diff shows why I believe this to be a problem in the opencv build system and not in the cvv module (the compare version works with the 2.4 branch): andreasBihlmaier/opencv_contrib@andreasBihlmaier:cvv_fix_docs...cvv_opencv_3.0.0

Compile error on RGBD modul (opencv_contrib)

Hi,
i report compile error on modules/rgbd/samples/odometry_evaluation.cpp
at line 38 and following

Here is a description :

these 3 include lines generate compile error
instead of

#include <opencv2/rgbd/rgbd.hpp>

i guess it should be

#include <opencv2/rgbd.hpp>

same remark for highgui and contrib includes

I have the following compilation error:

After correcting includes, i got this compile error
This must be related to missing opencv_XXX libraries links :

[Request] Release tag for corresponding OpenCV release

Currently there is no tag/branch in opencv_contrib, which makes it hard to identify which commit to build with specific opencv version. For example, opencv_contrib (master branch as of Oct 1st, 2014) cannot be built with opencv-3.0.0-alpha. Please consider add release tag for opencv_contrib as well as opencv.

fatal error: opencv2/ts/ts.hpp: No such file or directory - on the tag 3.0.0-beta

I have opencv-3.0.0-beta downloaded and opencv_contrib checked out at the tag 3.0.0-beta.

~/projects/vk_person_photos/opencv_build_gcc> git -C ../opencv_contrib/ status
HEAD detached at 3.0.0-beta
nothing to commit, working directory clean

CMake creates the Makefile successfully with the following command

cmake ../opencv-3.0.0-beta/ -DCMAKE_BUILD_TYPE=Debug -DWITH_QT=ON -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -G "Unix Makefiles"

But the building process (make) fails with this error:

And indeed, there is a file ts.hpp in opencv-3.0.0-beta/modules/ts/include/opencv2/ts.hpp, but it's not in ts directory as written in include.

Unknown CMake command "ocv_include_modules_recurse".

I tried to build the modules the same way you have mentioned but am stuck with this error

Command :

cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..

Error:

CMake Error at /home/tonystark/opencv_latest/opencv_contrib/modules/adas/tools/fcw_train/CMakeLists.txt:16 (ocv_include_modules_recurse):

Any idea how to fix this? please help me.

cv::viz::Mesh can't load .ply files as a rendered image

I am trying to render some data from .ply files and just use these codes:

viz::Mesh objmesh;
objmesh.load("/home/wangyida/workspaceEclipse/VizRender_src/Debug/mesh.ply");

But there is nothing loaded in objmesh, and the cloud and polygons are empty, is it a bug loading some particular .ply files since it is flexible in defining conponents?

changes in Basic HAL module affect the adas module

@mshabunin this pr of yours, I guess causes the adas module in opencv_contrib to fail, right? Or it doesn't have to do anything with that.

Policies and governantce model

I think that we need to find some policies and a governance model for opencv-contrib to let it to scale and having a decent QA of modules.

Cross compiling

Hi,
I've an issue when I try to recompile OpenCV (with contrib) for another architecture (mips). I tried opencv_contrib, downloaded from here as a zip, with OpenCV both 2.4.11 and 3.0.0-rc1.
With 2.4.11 (with linker options "-lstdc++ -lopencv_contrib -lopencv_core -lrt -lz -lm") it gives me an undefined reference to createEigenFaceRecognizer(), createFisherFaceRecognizer() and createLBPHFaceRecognizer(); I even tried to link each and every .a archive (from opencv_contrib to opencv_video), but without any success.
With 3.0.0-rc1 libopencv_contrib.a is not even created.
If it matters: in cmake-gui I've put the check in each entry 'BUILD_opencv_*' (apart highgui, which I don't think is needed as it's an embedded scenario, and opencv_world; to be honest I really need only face detection/recognition but for now linking everything is ok) and 'ENABLE_OMIT_FRAME_POINTER', specified (correctly, I checked it twice) 'OPENCV_EXTRA_MODULES_PATH', and deselected all the other entries. I noticed that, when I open cmake-gui again, the entry 'BUILD_FAT_JAVA_LIB' is now selected o_O
What am I doing wrong? Any suggestion?
TIA!

SIFT descriptor calculation: incorrectly depends on firstOctave == -1

I noticed that when computing a list of keypoints des1 = kps[0:n], and computing only des2 = list(kps[0]), I can get different values for des1[0] and des2[0] - which obviously shouldn't happen.

Digging a little bit into the problem, I found that the octave matters. As long as the list of keypoints to be described contains a keypoint with octave -1 (the lowest possible octave), everything is fine. If one list contains an octave of -1, but another list only has higher octaves, the identical keypoints are not identical anymore. It does not matter if the second list's firstOctave is at 0, 1 or higher; it only changes depending on the firstOctave being -1 or >= 0.

I think the root of the problem is that when calling createInitialImage, doubleImageSize is set to true if firstOctave < 0, and that upsampling changes the image significantly.

Temporary workarounds:

• hardcode firstOctave to -1 (requires recompiling)
• always add a keypoint with octave -1

descriptor.hpp and types.hpp needs inttypes.h

Although inttypes.h is a part of C99, VS2010 (and also 2005?) does not come with it. However descriptor.hpp and types.hpp explicitly need inttypes.h (independent of the "HAVE_INTTYPES_H" flag in cvconfig.h).

It would be better to either include inttypes.h as a source file, or make it optional based on HAVE_INTTYPES_H.

I believe the VS impl of inttypes.h can be found here: https://code.google.com/p/msinttypes/downloads/detail?name=msinttypes-r26.zip&can=2&q=

cannot install contrib modules

Hi all,
I tried to install Saliency module from contrib modules. I read the documents and tried Cmake commands as follows:
cmake -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=~/local -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules/ -D BUILD_DOCS=ON -D BUILD_EXAMPLES=ON -D WITH_CUDA=ON ..

After building, I cannot find saliency libraries or include files. It seems that my installation does not compile any contrib modules.
Thank you for your regards.

module reg - compilation problem(s)

Hello,

First I'd like to thank all of you, developers who shares freely your work to anyone, go on !

I want to compile and use the reg module. I try on windows 7 + MSYS + MinGW with opencv 2.4.8 and on linux/debian with opencv 2.4.9, same issues :
After some issues with some headers include ( opencv2/core.hpp => opencv2/core/core.hpp ) than I can handle, I got a fatal error during compilation :

/home/luc/projets/opencv/opencv-2.4.9/modules/contrib/modules/reg/src/mapperpyramid.cpp:93:25: error: ‘class cv::Ptrcv::reg::Map’ has no member named ‘get’

I don't know how to solve this problem. I don't know if I'm doing something wrong or if it is a bug in reg module.

Has anyone an idea to help me ? Thank you in advance !

About the naming of LatentSVM detector in opencv

Hi, I suggest to change the name of LatentSVM detector into DPM detector. As we know, latent svm refers to the training process of the deformable part-based model (DPM) but not testing. Currently, we haven't provided the training code of DPM in opencv, i.e., we acutally don't have a latent svm in opencv. 😄

Moving latentsvm test data into opencv_extra

Hi, I just noticed the test data of latentsvm are in opencv_contrib, under the module folder

Should we move the data into opencv_extra? In fact, after building opencv, the opencv_test_latentsvmdetector can not find these testing data.

rst_parser module not found when compiling matlab binding

I'm trying to follow the instructions here http://seevisionc.blogspot.com/2014/03/compiling-opencv-30-with-matlab-support.html for compiling with matlab bindings. In cmake, I get errors that the rst_parser is not found. I see the hdr_parser module is in the modules/python/src2 folder but I don't see any rst_parser. Is this a separate python module? If so, where is it available ( a quick google search didn't provide any results)?

Can't build with opencv-3.0.0 on Linux - Unknown CMake command "ocv_include_modules_recurse".

I am trying to build opencv with these extra modules, but CMake fails to generate Makefiles.

I run the following command

cmake ../opencv -DCMAKE_BUILD_TYPE=Debug -DWITH_QT=ON -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -G "Unix Makefiles"

and get the following error:

This cause segmentation fault during execution of fr_lfw_benchmark.cpp.

Class compilation troubles of the Matlab bindings

Good morning,

I would like to start with a thumb up on all the work made by the maintainers of the OpenCV and OpenCV-contrib projects.

As mentioned in this post, I have noticed the files corresponding to class bindings generated in modules/matlab/src/private/ are not compiled.
This behaviour is due to the following line in the modules/matlab/compile.cmake file

file(GLOB SOURCE_FILES "${CMAKE_CURRENT_BINARY_DIR}/src/*.cpp")
# [...]

After modifications to compiles the files in this private/ folder, I ran into various errors:

Firstly, I have seen in generator/templates/template_class_base.cpp:22

typedef std::vector<Bridge> (*)({{clss.name}}&, const std::vector<Bridge>&) MethodSignature;

I am not a C++ expert but I do not think it will generate valid C++. I think it should be:

typedef std::vector<Bridge> MethodSignature({{clss.name}}&, const std::vector<Bridge>&);
// or C++11 variant:
using MethodSignature = std::vector<Bridge> (*)({{clss.name}}&, const std::vector<Bridge>&);

Then, according to my compilers errors, I think the std::vector<Bridge>& input parameter should not be declared const.

According to some Ptr_XXX not defined, I guess this module is still a work in progress.

Environment used

• Ubuntu 12.04.2
• gcc 4.7.4

CMakeLists.txt in cvv module

-- General configuration for OpenCV 3.0.0-dev

Because MSVC compiler has only partial support for c++11 the compilation of cvv module fails on Windows with this compiler.

As a side note the flags

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -Wextra -pedantic")

should be changed to something like:

if(MSVC)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} /W3")
endif()
if(CMAKE_COMPILER_IS_GNUCC)
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wall -Wextra -pedantic")

bgsegm module description in README.md is misleading

In README.md file present in modules folder, the description of opencv_bgsegm module is provided as "opencv_bgsegm: Improved Adaptive Background Mixture Model for Real-time Tracking / Visual Tracking of Human Visitors under Variable-Lighting Conditions."

But, that is just the title of paper at http://goldberg.berkeley.edu/pubs/acc-2012-visual-tracking-final.pdf. The OpenCV implementation does only background/foreground segmentation and no tracking as such. For real time tracking the paper mentions use of bank of kalman filters which is not provided in the watered down version at bgfg_gmg.cpp. Only a part of the paper is implemented in OpenCV.

So could the description of bgsegm in README.md and inside modules/bgsegm be updated to "Statistical background image estimation and per-pixel Bayesian segmentation" ?. I could submit a pull request if required.

API consistency

Hi! As usual thanks for the outstanding work on OpenCV and contrib.
Is it possible to consider moving FAST, BRIEF and ORB under cv2.xfeatures2d like SURF and SIFT are? Or is there a specific reason I'm missing why they are in cv2 rather than the submodule. Thanks.

Problem outputMin outputMax in balanceWhite

After processing balanceWhite (xphoto /src/simple_color_balance.cpp), the values of the matrix it can not go into the range [outputMin, outputMax]

   Mat test(3,3,CV_32FC1);
    test.at<float>(0, 0) = 21000;
    test.at<float>(0, 1) = 24000;
    test.at<float>(0, 2) = 20000;
    test.at<float>(1, 0) = 21000;
    test.at<float>(1, 1) = 20000;
    test.at<float>(1, 2) = 20000;
    test.at<float>(2, 0) = 23000;
    test.at<float>(2, 1) = 20000;
    test.at<float>(2, 2) = 10000;
    double min1, max1;

                             0, 65536);
    cv::minMaxIdx(test, &min1, &max1);

In this example max1 = 76889.9 (mingw4.8.2)
When working with large matrices can greatly values go into the negative numbers
Thanks!

Error: no matching function for call to ‘cv::xfeatures2d::SURF::SURF(int&)’

'Morning.
I've installed over my already compiled and working OpenCV dist the opencv_contrib from this repository because im trying to use SURF.
The thing is that i've followed the steps from this page and is not working. It always returns me the same error.
Asking on the internet a guy told me that i need the library libopencv_xfeatures2d300.so but that file is not in the repo and it dosen't creates when i cmake.
The OpenCV forum is down and i'm a little desperate.
Anyone knows what is happening?
Thank you in advance.

updateMotionHistory, calcMotionGradient, calcGlobalOrientation not exposed to python/java

they're tagged as CV_EXPORTS_W in optflow/include/opencv2/optflow/motempl.hpp, but don't end up in the python or java wrappers.

this is probably due to a namespace problem, all other code is in namespace cv::optflow, the code from motempl.cpp in namespace cv::motempl

changing the namespace to cv::optflow, too will fix it, but feels like a gross change, hopefully someone has a better idea here.

linemod kinect magic number

I still see in linemod.cpp

@todo Magic number 1150 is focal length? This is something like

@vrabaud Do you know why we still have this fixed parameter in linemod? Is it real the focal length?

__popcnt not declared with mingw-w64 in bitops.hpp (line_descriptor modul)

Hi,

building with mingw-w64 leads to the error:

__popcnt is not declared in this scope

The error seems to be in the ifdef block in bitops.hpp:

#include "precomp.hpp"
#ifdef _WIN32
# include <intrin.h>
# define popcnt __popcnt
# pragma warning( disable : 4267 )
#else
# define popcnt __builtin_popcount
#endif

#define popcnt __builtin_popcount after the last #endifsolves the problem.

Possible solution:

#if defined _WIN32 && !defined __MINGW32__
# include <intrin.h>
# define popcnt __popcnt
# pragma warning( disable : 4267 )
#else
# define popcnt __builtin_popcount

mapperpyramid.cpp does not compile with opencv 2.4.9

Hi,
if i compile the library with visual c++ 2010, i got these message:

mapperpyramid.cpp
......\contrib\modules\reg\src\mapperpyramid.cpp(93): error C2039: 'get': Ist kein Element von 'cv::Ptr<_Tp>'
with
[
_Tp=cv::reg::Map
]

Thank you,
Steff

Surface Matching and x64 : heap corruption

Hi,

In surface_matching\src\ppf_match_3d.cpp a function "murmurHash" is used like the following :
KeyType hashKey=0;
murmurHash(key, 4*sizeof(int), 42, &hashKey);

In case of a 64bit system, "murmurHash" is defined via a macro as "hashMurmurx64" in surface_matching\src\hash_murmur.hpp
However this function takes a void* as a parameter which should at least of length (2*sizeof(unsigned int)). Here &hashKey is given, and hashKey is an unsigned int, thus there is a heap corruption.

A workaround consists in forcing "murmurHash" to be defined as hashMurmurx86 even on 32 bit system, but in this case I don't understand the purpose of specific code for x64 systems.

Regards,
Romain
