NOISE REDUCTION BASED ON MEDIAN ε-FILTER

Mitsuharu Matsumoto

Abstract

This paper describes a nonlinear filter, which can reduce the impulse noise with preserving the edge information labeled median ε-filter. ε-filter is a nonlinear filter, which can reduce the small amplitude noise with preserving the edge information. The algorithm is simple and it has many applications because it uses only switching and linear operations. Although it is difficult to reduce the impulse noise by using e-filter due to its features, we can reduce the impulse noise effectively with preserving the edge information by combining the concept of median filter and ε-filter. Due to its simple design, the calculation cost is relatively small the same as ε-filter. To show the effectiveness of the proposed method, we also report the results of some comparative experiments concerning the filter characteristics.
