Abstract:
1. A computer-implemented method for processing a photographic image, the method comprising: defining a first photographic image, said first photographic image characterized by multiple pixels and including depiction of an object, said defining of said first photographic image including formulating a first pixel matrix, said first pixel matrix representing pixels having pixel intensities in a spectrum between black pixels and white pixels; defining a second photographic image, said second photographic image characterized by said multiple pixels and including depiction of said object, said defining of said second photographic image including formulating a second pixel matrix, said second pixel matrix representing black pixels and white pixels, said formulating of said second pixel matrix including establishing a threshold pixel intensity for designating each pixel in said first pixel matrix as either a black pixel or a white pixel in said second pixel matrix; delineating a boundary of said object, said delineating including formulating a third pixel matrix, said third pixel matrix representing pixels located at interfaces between white pixels and black pixels in said second pixel matrix; comparing the delineated said boundary of said object to said object depicted in said second photographic image; repeating, at least once, said defining of said second photographic image, said delineating of said boundary of said object, and said comparing of the delineated said boundary of said object to said object depicted in said second photographic image, wherein in each said repetition a different said threshold pixel intensity is established in performing said defining of said second photographic image.
