Abstract

Chain coding families are a collection of line drawing representation techniques which use the square grid for sampling and quantization. They include chain codes, generalized chain codes, and polycurve codes. For optimal selection among these techniques, it is important to investigate the properties of the chain coding families. In this paper, we evaluate comparatively precision of chain coding families by applying a stochastic line drawing model. Experimental results show that polycurve codes improve precision over chain codes and generalized chain codes.
