In this paper an exhaustive study of despeckling techniques used for ultrasound images that are available in the literature is carried out. Noise removal from Ultrasound images still remains a challenging task for the image processing experts. The huge amount of research papers published in this area stands as a testimony to it. Generally there's no unified approach for the removal of noises in US images. In this paper different types of most prominent existing speckle noise reduction techniques both in Spatial or Space domain and Frequency or Transform domain are discussed and compared.
