This paper describes an intensity image filter for computing the variance of pixel values contained within a neighborhood centered at each input pixel. The output image contains the calculated variance at each input pixel location. Variance calculations can be restricted by setting an image mask. This paper is accompanied with source code for the filter and test, test images and parameters, and expected output images.
