Standard Deviation Definition
Occasionally I see a request for computation of a running, windowed standard deviation. This is easily accomplished using filter and the alternative formula for the standard deviation:std = sqrt((sum(x.^2) - n*xbar.^2)/(n-1)).Movingstd allows you to specify forward, backward or central windows of...

The program transforms an input image using the differential box counting algorithm to a fractal dimension (FD) image, i.e. each pixel has its own FD. Then the user can select any region of interest in the generated FD image to estimate the corresponding mean, standard deviation and lacunarity.
