This paper provides the derivation of speckle reducing anisotropic diffusion [SRAD], a diffusion method tailored to ultrasonic and radar imaging applications. SRAD is the edge-sensitive diffusion for speckled images, in the same way that conv

基于各向异性扩散的几种平滑算法比较及改进，对图像平滑算法的研究有很大的参考价值！-Anisotropic Diffusion Based on the comparison of several smoothing algorithm and the improvement of the image smoothing algorithm have great reference value!
