主 题:anisotropic diffusion filter ultrasound speckle reduction
摘 要:Speckle noise has long been known as a limiting factor for the quality of an ultrasound B-mode *** this study,anisotropic diffusion filtering is proposed as an effective method for ultrasound speckle *** article provides a brief description of anisotropic diffusion filtering proposed by Perona and Malik,and compares its speckle filtering effects with other filtering methods including median,moving average,and frequency domain Gaussian *** this study,multiple filters are implemented in *** each filter,three different types of noisy images with speckle noise are *** results show that anisotropic filter can reduce the noise more effectively and meanwhile preserve the boundaries of the *** addition,this filter has more controllable filtering parameters and is independent on the information of the noise.
