%X The Ultrasound images are usually degraded by speckle which brings much difficulties in diagnosis and treatment.In noisy images,the Gaussian convolution is often applied to smooth image and then gray differential is calculated to detect image edges.A structure tensor based on Gaussian convolution is devised and introduced to anisotropic diffusion in order to reduce speckle.Experiment shows that the novel anisotropic diffusion based on structure tensor can reducing speckle,detect and preserve edges and useful details effectively.
