Speckle Noise Reduction from Medical Ultrasound Images-A comparative study

In medical image processing image denoising has become a very essential exercise all through the diagnose. Medical images are often deteriorated by noise due to a serious sources of interferences and other phenomenon that affect the measurement process in an imaging and acquisition system. Speckle noise is a random mottling of the image with bright and dark spots, which obscures fine details and degrades the delectability of low contrast lesions. Speckle noise occurrence is often undesirable since it affects the tasks of human interpretation and diagnosis. Speckle noise is a granular noise that inherently exists in and degrades the quality of the images. Generally it is found in Ultrasound image and radar image. Various noise removing methods has been introduced. This paper run a comparative study on various filter efficiencies in removing speckle noise from medical ultrasound images using statistical measures.
