Paper Abstract

The basic operations of mathematical morphology are quite useful for a broad area of image processing and analysis tasks. All morphological operations can be built from erosions and dilations. In this paper we develop a single chip VLSI architecture of an erosion/dilation algorithm for real-time image processing. The new architecture allows sequential inputs and performs parallel processing with 100 percent efficiency. The erosions (mm of differences) and dilations (max of additions) operate on 2-D gray-level image signals and use a 5 x 5-pixel gray-level structuring element. Two chips can be cascaded for a 7 x 7 structuring element. The overall chip design also provides the user with sufficient flexibility to optionally offset the output images by adding a constant level and/or scale their dynamic range. 1.
