Abstract:
1. A computer program product, tangibly stored on a computer-readable medium, for finding edgeless areas in a digital image, comprising instructions operable to cause a programmable processor to: select from a digital image an unexamined pixel from said digital image P using a start rule luminance tolerance, if the range of luminance values of the major neighbors of the selected pixel is less than said start rule tolerance, calculate the average luminance of p run a first inclusion rule to attempt expansion of said edgeless area if possible; repeat the preceding steps until there are no more unexamined pixels not in an edgeless area; using a first inclusion rule tolerance IR for any major neighbors of P repeat the foregoing steps of said first inclusion rule for each pixel added to said edgeless area by operation of said first inclusion rule; produce a table of pixels within said digital image which are within at least one edgeless area.
