Abstract
Current ultrasound image denoising algorithms cannot maintain edge well while denoising.An improved anisotropic diffusion denoising method called anisotropic diffusion based on Logarithmic Compression(LCAD) was proposed to reduce ultrasound speckle noise after the study of anisotropic diffusion model.The proposed method estimated noise distribution model after logarithmic compression of the image and then generated a diffusion coefficient based on generalized Gamma distribution to achieve denoising purpose while diffusing.
