Abstract:
A method of image processing, comprising the steps of:(a) obtaining image data as a plurality of pixels, each of the plurality of pixels having at least two indices, and having an assigned value, wherein said assigned value corresponds to a texture; (b) for said each pixel, calculating a plurality of summed assigned values, each of said plurality of summed assigned values obtained from a plurality of subsets of pixels away from said each pixel, each of said plurality of summed assigned values having an amplitude and a direction; (c) calculating and assigning a composite summed assigned value and a composite direction to said each pixel as a plurality of composite assigned values; and (d) displaying said plurality of composite assigned values as an image; wherein said texture is obtained by: for said each pixel, selecting a first set of surrounding pixels and obtaining a first composite intensity from said first set of surrounding pixels; for said each pixel, selecting a second set of surrounding pixels and obtaining a second composite intensity from said second set of surrounding pixels; and obtaining said texture which is a ratio of said first and second composite intensities, and assigning said texture to said each pixel.
