Pipeline architecture for compound morphological operators

Abstract : In this paper we present a new pipeline HW architecture for fast 2-D erosions/dilations. The implementation is based on a recently proposed algorithm allowing to process 2-D data in a stream, minimizing the use of memory and drastically reducing the computing latency. These elementary operators can be chained in an efficient pipeline to realize compound morphological operators (opening, closing, ASF filters, etc.) with no intermediate image storage and minimal latency.
