Abstract :
A class of quantization schemes is presented which generalizes various existing chain coding methods. For the general case, simple expressions are derived for the probabilities of the directional elements from which we can determine the number of curve points and the length of the quantized curve. These results allow for the comparison of performance of the various encoding schemes.
