| Abstract(in English) | In this study, we propose a random-valued impulse noise removal method with superior detail preservation capability by an extended median filter. This filter uses both a median filter with a square window and that with an adaptive one constructed by using 8-neighborhood minimum spanning tree (MST). Median filter with a square window has superior capability in the impulse noise removal. However, it tends to destroy detailed structure in an image. To cope with this problem, the proposed method calculates a weighted median by using the pixels both in the square window and the adaptive one which fits to the details in the image. In this paper, the superior performance of the proposed method is verified through the experiments with gray-scale and colored natural and artificial images by comparing with some MST-based noise removal methods. |
