I have an image and I want to calculate the average pixel value of that image, i.e. the value at each pixel is the average value of neighbourhood pixels' intensities in 3*3 window of the image. Therefore, for every pixel, we have to take the mean of its neighbourhood pixels' intensities.
Does anyone know how to do this in matlab?
