Hi guys, I would like to know ho to create a sliding window in a matrix. Thank you very much.

You can use conv2() or imfilter(). For example:

windowWidth = 11;
kernel = ones(windowWidth, windowWidth) / windowWidth ^ 2;
smoothedImage = conv2(double(grayImage), kernel, 'same');

Undefined function or variable 'grayImage'.

Replace grayImage with the variable that stores your gray-scale image (not RGB)
