Median and rank order filters are very important types of filters in image processing well known for their ability in removing impulse noise and preserving the edges of the image. The computational power of Digital Signal Processing is growing rapidly due to advances in VLSI technology and processor architectures. It is possible to design high performance hardware filters by using recent VLSI technique. Fast, powerful and efficient hardware design for these filters is very important. In this paper, weighted median filter architecture that has a great potential to be used in image processing is implemented. This architecture is pipelined bit-serial systolic design that provides the real time application requirements .This architecture also includes median filter implementation and is not limited to only weighted-median filter but can be extended to perform adaptive length and recursive weighted median filtering operations. |
