Since, there is no common filter for speckle reduction. In this paper, we proposed six nonlinear techniques with combiner approach for image filtering especially for speckle removal task, viz., MNHP Filter, ANHP Filter, TNHP Filter, MMNHP Filter, AMNHP Filter and TMNHP Filter. The proposed filters are evaluated and compared to achieve using their performance on ultrasound breast cancer images.
