OpenCV Interface Support

MEX-file support for OpenCV library functions

The support files provide an OpenCV Interface C++ API for integrating your OpenCV C++ code into MATLAB^®. You can also use these support files to build MEX-files that call OpenCV functions. The support files contain graphics processing unit (GPU) support.

See Install and Use Computer Vision Toolbox OpenCV Interface procedures and examples.
