BACKGROUND Speckle noise removal is the most important step in the processing of echocardiographic images. A speckle-free image produces useful information to diagnose heart-related diseases. Images which contain low noise and sharp edges are more easily analyzed by the clinicians. This noise removal stage is also a preprocessing stage in segmentation techniques. METHODS A new formulation has been proposed for a well-known nonlinear complex diffusion filter (NCDF). Its diffusion coefficient… CONTINUE READING
