Abstract :
A model for line-drawing graphics is presented to study the performance of chain coding, such as quantisation distortions and coding rates. A differential angle distribution of line drawings is proposed based on this model and verified by experiments. The distribution is necessary for the analysis and design of differential chain coding.
