An IDBUTM Filter for the Removal of High Density Impulse Noise
Shivpratap Pandey, Kunal Gaurav, Piyush Kumar Sharma · 2014
Improved decision based unsymmetric trimmed median filter is one of the valuable methods that are capable to restore of gray scale images which have been enormously corrupted by Salt-and-Pepper noise. An Improved decision based unsymmetric trimmed median filter is proposed to enhance decision based unsymmetric trimmed median filter in term of its noise filtering ability as the images are highly degraded. In the case of high density noise, the presentation of the standard methods is very poor in terms of noise restraint and detail preservation. This filter has proved its supremacy in preserving edges and fine details over the other well-known filters. This algorithm shows better results than the Median Filter (MF), Progressive Switched Median Filter (PSMF), Adaptive Median Filter (AMF) and Modified Decision Based Unsymmetric Trimmed median filter (MDBUTMF) at high Impulse noise density.
