Hybridization of Non Linear Algorithms in MR Images

摘要

Magnetic Resonance Imaging (MRI) is most popularly used techniques in medical imaging. There are various non linear algorithms available to remove rician noise in images.The main aim of each filter is to preserve qualitative data of image. In literature, existing algorithms were not achieving the goal of preserving fine details and edges simultaneously. UNLM conserve most of details and ADF conserves edges. So the idea is to combine both the technique to take advantage of both simultaneously. The proposed method preserves both edges and details simultaneously irrespective of level of noise present on images.
