Abstract

A new speckle reduction method for ultrasonic images is presented. The proposed approach exploits the knowledge of multiplicative speckle model and a regularization scheme is applied to diffusion processing. The nonlinear diffusion is integrated with dyadic wavelet transform. Experimental results show the new algorithm can not only reduce speckle effectively, but also preserve and even enhance edge and details.
