Subjective and objective evaluations of feature selected multi output filter for speckle reduction on ultrasound images. Phys Med Biol. 2018 Aug 21;: Authors: Outtas M, Zhang L, Deforges O, Serir A, Hamidouche W, Chen Y Abstract Ultrasonographic examination, either as visual inspection or quantitative
 analysis, is the most widely diagnostic resource. However, speckle noise is
 one of the drawbacks that makes it less effective than other medical imaging
 systems. Several speckle reduction methods often offer effective speckle reduction
 but generally suffer from oversmoothing, a blurring effect and a man-made
 appearance. In this paper, we propose a Multi-Output Filter based on the Multiplicative
 Multiresolution Decomposition (MOF-MMD). This multi-scale based
 method enables the enhancement of the original image and provides three enhanced
 outputs: global, edge and texture images. The multi-output filter aims
 at offering an enhanced image according to the features desired by radiologists.
 The different structures, textures and edges are filtered according to the contour
 image obtained by morphological operators. Three radiologists with different
 years of experience, have subjectively evaluated the speckle reduction methods
 according to enhanced features. The results of objective metrics and subjective
 evaluation sho...
