摘要：In this paper, a detailed description and comparison of speckle reduction of medical ultrasound is presented. Four speckle reduction filters are described in a detailed fashion to facilitate implementation for research and evaluation. The filtering techniques considered include Lee,Kuan,Frost and Oriented Speckle Reducing Anisotropic Diffusion(OSRAD). These filtering techniques are applied to a 2D liver image and respective de speckled images are obtained. Application of objective quality metrics quantifies the preservation of image edges, overall image distortion, and improvement in image c ontrast. It is concluded that the optimal method is the OSRAD diffusion filter. This method is capable of strong speckle suppression with less computational complexity
