High speed implementation of 1-D and 2-D morphological operations

The design of a morphological processing system is presented, to be used in medical image enhancement and compression. The system consists of a gray scale dilation/erosion systolic array capable of video data rates. The architecture can be implemented with either one dimensional or two dimensional building blocks that accept raster scanned data and exhibits low latency and an optimal pipeline rate. Two processing element designs are presented, one based on programmable gate arrays and one suitable for standard cell VLSI implementation
