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

What do you have so far? Do you have the camera already? If so, what king? Do you have the Image Acquistion Toolbox (I'm not even sure if it's needed or works with Simulink so call Mathworks and ask them)? Are you able to pull an image in from the camera to a variable in your code or Simulink block yet?

I have the camera, the kind is "web camera Full HD 1080P" and I can open it, I dont no how to extract in Simulink the I matrix, the Pixel matrix.

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
