METHOD OF REMOVING NOISE IN IMAGE, ELECTRICAL DEVICE, AND STORAGE MEDIUM

A method of removing noise in an image includes calculating, for each pixel in the image, a defect weight indicating a correlation between pixel and its neighboring pixels; calculating, for a target pixel in the image, a matching weight indicating a similarity between a target block centered on the target pixel and a reference block centered on a reference pixel located within a search range from the target pixel, the matching weight being calculated by means of the defect weight; and calculating a filtered value of the target pixel based on a value of the reference pixel and the matching weight between the target block and the reference block centered on said reference pixel.
