SPECKLE NOISE REMOVAL IN MEDICAL IMAGES USING CLUSTER BASED FILTER ALGORITHM

Abstract

Medical images especially ultrasound images are easily prone to noises like specklenoise, which is
multiplicative in nature. It degrades the image quality and contrast . Hence there is an need for speckle
noise reduction. There has been many filters available for speckle noise reduction. In this paper we
discuss about the speckle noise removal using cluster based filters. Clustering method is suitable for
image segmentation and identification.
