Small Computer Vision Library.
- Lightweight
- C++11 based
- Not including optimization
- Conformance
- API like OpenCV
- Same result on PC and Android
Supported:
Mat
imread()
/imwrite()
/imshow()
/waitKey()
cvtColor()
/resize()
putText()
/rectangle()
/circle()
/line()
Not supported:
Mat::clone()
saturate_cast
parallel_for_
operator Point_<Tp2>
To build this project, you are assumed:
- Familiar with CMake based C/C++ building
- Install glfw for
imshow()
. See deps/glfw_build for build hints. - Modify cmake/deps.cmake to specify dependencies paths.
