Abstract: Denoising medical images is often required for efficient diagnosis of the diseases. Total Variance (TV) is employed as a model of partial differential equation to identify the isolated noisy regions in the image. In the due course, the TV has been modified to various versions. In this study, a performance analysis of adaptive TV, median filtering and modified TV is performed, brain MRI of a patient subjected to tumour is considered for denoising process. Later the same is segmented to have a clear vision of the tumour portion. The simulation is carried out in MATLAB using image processing tool box. The evaluation is carried out using performance metrics like PSNR.
