Speckle noise is the inherent property of ultrasound B-Scan images which has been filtered using well-established speckle reduction techniques. In this work, six spatial filters namely Frost, Median, Lee, Kuan, Wiener, and Homomorphic filters, and two diffusion filters viz., Speckle Reduction Anisotropic Diffusion (SRAD) filter, and Anisotropic Diffusion (AD) filter have been attempted over 200 different digital ultrasound B-scan images of kidney, abdomen, liver and choroids. A comparative… CONTINUE READING
