This is a formula for LoG filtering: alt text

Also in applications with LoG filtering I see that function is called with only one parameter: sigma(s). I want to try LoG filtering using that formula (previous attempt was by gaussian filter and then laplacian filter with some filter-window size ) But looking at that formula I can't understand how the size of filter is connected with this formula, does it mean that the filter size is fixed? Can you explain how to use it?
