MATLAB: How to use the Computer Vision System Toolbox OpenCV Interface

Question

Hi,

I've download the OpenCV 3.1.0 and correctly installed the Computer Vision System Toolbox OpenCV Interface. I followed these instructions:

The whole process was ok, the examples run properly.

Now, I'm very confused, because I'm trying to run the built-in functions of OpenCV in Matlab, but I can't understand how. It seems like there is no way to do this. Some sources tell that I have to write the C++ code myself, but I don't know the C++ language. Instead this link confirms that it is possible:

My purpose is to use the feature detector, to extract keypoints from an image using the Harris corner algorithm.

Please, could someone help me? I need a guide… which OpenCV functions I have to call? How?

Thank you very much, kind regards.

If you just want to use Harris corner detection algorithm, try detectHarrisFeatures function to do this. You don't need coding a C++ wrapper.
