Asynchronous Relaxation of Morphological Operators: A Joint Algorithm-Architecture Perspective

Abstract

Asynchronous dynamics are introduced for the iterative computation of morphological image filters. We propose a fine-grain asynchronous algorithmic- architectural model that exploits these new possibilities to improve the convergence efficiency of such operators over standard sequential-recursive or parallel-synchronous update modes. We conclude with VLSI design perspectives and show how asynchronism can be exploited both at functional and architectural levels.
