Abstract
A new conditional differential chain coding (CDCC) scheme is presented for lossless representation of an object contour. It uses the conditional probability of directional symbols depending on the context of preceding contour directions. Experimental results show that the CDCC reduces coding bits by 5-10% when compared with the conventional differential chain coding (DCC) which does not use conditional probability
