Relative Effectiveness of Selected Texture Primitive Statistics for Texture Discrimination

Three simple methods of extracting texture primitives are compared. It appears that the simplest of these, thresholding at a fixed percentile, yields primitives that are quite effective in texture discrimination, using a set of simple properties of the primitives. Second-order statistics of these properties were also computed for pairs of neighboring primitives, using several definitions of "neighboring." In some cases, textures not discriminable using first-order statistics can be discriminated using statistics of the second order.
