Survey on Speckle Filtering Techniques of the Ultrasound Images
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
Today, ultrasound and magnetic resonance images are the essential tools for non-invasive medical diagnosis. One of the fundamental problems in this area is speckle noise, which is a major limitation on the image quality particularly in ultrasound imaging. Ultrasound images contain speckle noise that affects the quality of images. The presence of speckle noise affects image interpretation by human and the accuracy of the computer-aided diagnosis techniques. Low image quality is an obstacle to an effective feature extraction, analysis, identification and quantitative measurements. Speckle is a granular noise that is naturally present in and degrades the quality of medical images. Eliminating such noise is an important pre-processing task. This paper presents a review of some important work for removing stains from ultrasound images.
