FASTCV API——Using to support Parrots

fastcv_api : fastcv api

fastcv_api, is API of fastcv, it make fastcv to use some platforms, such as X86, ARM, NVIDIA GPU, OpenCL and so on. Then you can use X86/ARM and CUDA together. OCL doesnot provide temporarily.

Prerequisites

fastcv has several dependencies.

• CUDA is required for GPU CUDA mode. (>=7.0)
• OPENCL is required for OpenCL mode.
• gtest is required for unit test. (>=1.7)
• OpenCV is required for unit test. (>=2)
• CMake is required for compilation. (>=2.8)

Support

Until now, fastcv_api has provided many basic image operations, which mainly contains image resize, convertTO, warpAffine, serveral filters, gaussianBlur, integral, crop, cvtColor, etc.

The library is still in updating. We hope our fastcv_api is strong enough to replace opencv.

Installation

• post_release_lib: The dependant project named with post_release_lib is needed, which provides basic libiary. And post_release_lib should be installed in the same directory with fastcv_api project. if link library is failed, please check the library whether in this project. [email protected]:lijiabin/post_release_lib.git
• bcl: The dependant project named with bcl is needed when you build fastcv_api in opencl mode. And bcl should be installed in the same directory with fastcv_api project.

Complilation

Options

• USE_CUDA : whether to build on CUDA and x86/ARM device. (default: OFF)

• USE_OPENCL : whether to build on opencl and x86/ARM device. (default: OFF)

• USE_CPP11 : whether to open C++11 supported. (default: ON)

• BUILD_ARM : whether to build on ARM platform. (default: OFF)

• BUILD_ANDROID : whether to build on android platform. (default: OFF)

• BUILD_IOS : whether to build on ios platform. (default: OFF)

• BUILD_IOS_SIM : whether to build on ios sim platform. (default: OFF)

• BUILD_WINDOWS : whether to build on Windows. (default: OFF)

• ARM_ARCH : specify ARM architecture. (accepted value: ARMV7 or ARM64)

Notice:

- USE_CUDA and USE_OPENCL can't be setted on both at the same time.
- BUILD_ANDOIRD and BUILD_IOS can't be setted on both at the same time.
- Only one of USE_CUDA, USE_OPENCL, BUILD_ANDROID, BUILD_IOS can be setted on at the same time.

Linux and Mac System :

• cd fastcv_api && mkdir build && cd build
• cmake ..
• make

Android Please modify CMakeList.txt to set variable ANDROID_TOOLCHAIN_ROOT which is android cross compilation tools directory.

• cd fastcv_api && mkdir build && cd build
• cmake -D BUILD_ANDROID=ON -D ARM_ARCH=ARMV7|ARM64 ..
• make

IOS Please modify CMakeList.txt to set variable CMAKE_OSX_SYSROOT which is ios sdk directory.
