Abstract: “Speckle reducing anisotropic diffusion (SRAD), a diffusion method tailored to ultrasonic medical imaging and radar imaging applications. In SRAD the instantaneous coefficient of variation is derived by taking account only 4 pixel of image. We proposed the new algorithm using SRAD that consider 8 neighbor pixel of image i.e. horizontal and diagonal pixel both. We also demonstrate the algorithm performance on some ultrasound image. The performance measures obtained by is considerable compare to existing noise reducing algorithm and better edge preservation, variance reduction, and edge localization.”
