Abstract: In this paper, fuzzy based median filtering technique is proposed for enhancing highly corrupted digital images. This filter is obtained in two steps; in first step fuzzy decision rule is applied to detect the impulse noise on input image (noisy image). In second step, noisy pixels are removed using decision based filters. The performance of proposed filter is compared with other existing filters and shown to be more effective in terms of eliminating impulse noise and preserving edges and fine details of digital images.
