ABSTRACT:
A method of computing neighborhoods of pixels which neighborhoods are bounded to include particular image characteristics including using the digital image to compute neighborhoods of pixels which are to be processed and wherein such neighborhoods of pixels are substantially bounded by pixels defining the particular image characteristic; computing an activity number for each pixel based upon the values of adjacent pixels; using the activity numbers for each pixel and activity numbers for adjacent pixels in a predetermined neighborhood to produce a plurality of trend numbers for each pixel related to the particular image characteristic; and using the trend numbers for each pixel to determine the neighborhoods of pixels which bound the particular image characteristic.
