Optimal Dynamic Quantizers for 2D Systems with Discrete-valued Input and Its Application to Generation of Binary Halftone Images

Abstract

This paper addresses an optimal design problem of dynamic quantizers for a class of 2D systems with discrete-valued input. First, we derive a closed form expression of the performance of a class of dynamic quantizers. Next, based on this, an optimal dynamic quantizer and its performance are provided. Finally, we apply the optimal dynamic quantizer to generate binary halftone images.
