Images are often corrupted by impulse noise in the procedures of image acquisition and transmission. In this paper, an efficient VLSI implementation of Adaptive Rank Order Filter (AROF) for removal of impulse noise is proposed. The algorithm removes noise without degrading the image information. The AROF VLSI architecture implements pipelining with parallel processing in order to speed up the filtering process. The performance of proposed algorithm is compared with Decision Tree Based Denoising Method (DTBDM).
