Distance set and turning point are chosen from the shape contour,and coded by DPCM. So the 2-dimensional data can be described by 1-dimensional data,and K K reduce the bit streams effectively. The algorithm can adapt to every particular boundary trend,and gives a better reconstructed effect.The reconstructed shape only has a geometrical error,and can overcome the ladder effect which always appears in the block-based shape coding. %K distance set %K turning point %K baseline %K shape coding
