Abstract

One of the most important features in image analysis and understanding is shape. Mathematical morphology is the image pro- cessing branch that deals with shape analysis. The definition of all morphological transformations is based on two primitive operations, i.e., dilation and erosion. Since many applications require the solu- tion of morphological problems in real time, researching time effi- cient algorithms for these two operations is crucial. In this paper, efficient algorithms for the binary dilation and erosion are presented and evaluated for an advanced associative processor. Simulation results show that the proposed algorithms for this advanced archi- tecture reach a near optimal speedup compared to the serial algo- rithm. Additionally, it is proven that the implementation of this image processor is economically feasible. © 2001 SPIE and IS&T.
