This tool assigns each cell in the output grid the number of different values in a moving window centred on each grid cell in the input raster. The input image should contain integer values but floating point data are allowable and will be handled by multiplying pixel values by 1000 and rounding. Neighbourhood size, or filter size, is specified in the x and y dimensions using the filterx and filtery flags. These dimensions should be odd, positive integer values, e.g. 3, 5, 7, 9... If the kernel filter size is the same in the x and y dimensions, the silent filter flag may be used instead (command-line interface only).
