Block-based parallel image thinning methods, computer program products and systems

Abstract

A block-based parallel image thinning method segments an input image into blocks, determines the block flag of each of the segmented blocks, and determines a preservation condition of an object pixel of a corresponding block. Then, the method determines a removal condition of the object pixel for which the preservation condition has been determined, removes the value of the object pixel satisfying the removal condition and sets the block flag. When all the blocks have been thinned, the method thins the processed image into one-pixel thickness using a post processing condition. Related systems and computer program products also are provided.
