In recoding with three bits the pixels of objects in binary images according to some measure of distance to the background, parallel thinning is achieved using syntactic rules. The codes in a 3 x 3 window are searched for interrelations which determine the new code of the central pixel. The local structure of the codes is determined through a binary cascade of tables. To each structure corresponds a rewriting rule. The new code is the output of the cascade. A two-scan postprocessing is needed… CONTINUE READING
