Windows DLL available to download

I am pleased to announce that this extension is now compiled for Windows by the PHP Extension Repository site.

You can download the DLLs on the extension page: https://phpext.phptools.online/extension/system/facedetect-428

If you have any questions, I am available to discuss them.

Fail to install : undeclared identifier 'CV_VERSION'

Hello,

I try to install PHP-Facedetect on my Mac (OSX 10.11.1) but it fails.

I did install opencv3 using homebrew :

$ brew install opencv3 --with-contrib
$ brew link opencv3

Then tried to build the PHP-Facedetect extension

missing tags and versions

could you please tag and version your extension. i'm trying to package it into distribution

i.e git tag and push it to github, so tagged release tarballs could be downloaded

no release available for package facedetect (pecl install)

Package is not available .... ? tnx

Error 500 when trying to detect a face

Hi,

after some couple of hours I managed to install everything on my Debian Wheezy.
But I receive following error, no matter which cascade I'm trying to load

OpenCV Error: Unspecified error (The node does not represent a user object (unknown type?)) in cvRead, file /root/opencv-2.4.9/modules/core/src/persistence.cpp, line 4991
terminate called after throwing an instance of 'cv::Exception'
  what():  /root/opencv-2.4.9/modules/core/src/persistence.cpp:4991: error: (-2) The node does not represent a user object (unknown type?) in function cvRead

Do you have any idea whats going on? There are hundreds of poeple with this issue but only workarounds for java - not php. Any idea? PHP 5.4 on Debian Wheezy, (fgci)

face_count & face_detect not working

Hi,

i have installed all like you wrote and the facedetect class is also in my php.ini but if I want to try it with

var_dump(face_count('1_1.jpeg', 'haarcascade_frontalface_alt.xml'));
var_dump(face_detect('1_1.jpeg', 'haarcascade_frontalface_alt.xml'));

I only see bool(false) bool(false) nothing else. I have tried it with several pictures.
I don't know where mistake is.

PHP.ini shows:
facedetect
facedetect support enabled
facedetect version 1.1.0
OpenCV version 2.4.3

facedetect.so: undefined symbol: _emalloc_56 in Unknown on line 0

php5

Can't stop "Apache HTTP Server"' when extension is enabled

I got this bug report [1] from Fedora 23, I try update to php-facedetect-1.1.0 and still verify that http
shutdown just stop after timeout , instead be quickly.

[1] https://bugzilla.redhat.com/show_bug.cgi?id=1292385

execution time

i have the problem that "haarcascade_profileface" runs sometimes very long...

is there a way to limit the execution time of a call?

Face recognition support

It would be nice to have a face recognition feature after face detection so we can compare faces between images (detect / train / recognize).

Any solutions?

feature request: OpenCV 3

They say OpenCV 3 has great improvements regarding face recognition. It would be great to see how it works with OpenCV 3.

OpenCV 4.1.2 and PHP-Facedetect

Hello.

this problem is happening. Has anyone managed to make it work? I am using debian testing (pureOS byzantium). on debian buster (pureOS amber) it is 100%. debian testing upgraded from version 3.2 to version 4.1.2 of OpenCV and facedetect broke.

Thanks.

PHP Startup: Unable to load dynamic library !

Whenever I try to restart apache now I get the following error:

  PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20131226/facedetect.so' - /usr/lib/php5/20131226/facedetect.so: undefined symbol: cvLoadImage in Unknown on line 0

An ofcourse it won't work since it wasn't loaded !! Any clue what went wrong ?

PHP Version 5.6.17
OpenCV Verison 3.1.0

PHP7

Hello,

I was able to compile this extension for PHP 7 using opencv3 on osx and debian jessie.
I had to

wget https://github.com/Itseez/opencv/raw/master/modules/objdetect/include/opencv2/objdetect/objdetect_c.h -O /usr/local/include/opencv2/objdetect/objdetect_c.h

in order to pass the ./configure step, and then the facedetect.so compiled, but I cannot use it :

As soon as I try to face_detect I get this fatal error :

symbol lookup error: /usr/lib/php/20151012/facedetect.so: undefined symbol: MAKE_STD_ZVAL

Is this a “normal” bug related to PHP7 and PHP-Facdetect ?

error message while ./configure

Hi..today, I'm trying to compile this great extension, but got the following error message

checking /usr/local/include/opencv/cv.h usability... no
checking /usr/local/include/opencv/cv.h presence... no
checking for /usr/local/include/opencv/cv.h... no
configure: error: 'opencv/cv.h' header not found

I've installed opencv 2.3.1 on my FreeBSD 8.2 box by using FreeBSD port tree, while checking /usr/local/include/opencv/cv.h, the header is exist there. I have no idea what's wrong, do you have any advice?

thank you / Ben

Where to download cascade.xml ?

Is this one ?

https://code.ros.org/trac/opencv/browser/trunk/opencv_extra/testdata/cv/cascadeandhog/cascade.xml

Happy to know someone has wrapped OpenCV in php extension!! Great Job!! Thank you!!
