Hi.
I want to open the camera that will work on grayscale with the help of the "from Video Device" in Simulink and extract from each frame its I matrix.
Thanks

Double click on the block and change the output color space option to "grayscale" if you can. Or, the Computer Vision Toolbox offers a Color Space Conversion block. Or, use a MATLAB function block to wrap the rgb2gray in Simulink, this is part of basic MATLAB. Or just do it your self, since intensity of RGB is just sqrt(R^2 + G^2 + B^2).

Sorry, my question was not understood.
I have a camera and I know how to open it to do a grayscale photo, my question is how do I extract in simulink the matrix I, the pixel matrix of the image
thanks
