A 2-D Adaptive Trimmed Mean Autoregressive (ATMAR) model has been proposed for denoising of medical images corrupted with poisson noise. Unfiltered images are divided into smaller chunks and ATMAR model is applied on each chunk separately. In this paper. two 5x5 windows with 40% overlapping are used to predict the center pixel value of the central row. https://darthomes.shop/product-category/lockers/
