Methods and systems which provide object edge image representation (650) generation using block based edgel techniques implementing post edgel detection processing to eliminate false edges are provided. The methods comprise subdividing image data to facilitate separate edgel detection processing of a plurality of sub-blocks (631-638) of the image data. A false edge elimination algorithm is applied in recombining the object edge image representation sub-blocks (641-648) resulting from the sub-block edgel detection processing to eliminate false edge artifacts associated with use of block based edgel detection.
