Denoising of Computer Tomography images using Wavelet based Multiple Thresholds Switching (WMTS) filterBy Mayank Chakraverty, Ritaban Chakravarty, Vinay Babu, Kinshuk Gupta
Abstract: Computer Topography images are often corrupted by salt and pepper noise during image acquisition and /or transmission, reconstruction due to a number of non-idealities encountered in image sensors and communication channels. Noise is considered to be the number one limiting factor of CT image quality. A novel decision-based filter, called the wavelet based multiple thresholds switching (WMTS) filter, is used to restore images corrupted by salt-pepper impulse noise. The filter …
