Method and system for filtering noises in an image scanned by charged particles

摘要

A method for filtering noises in an image scanned by charged particles includes steps of grouping pixels with similar types in the image into a plurality of pixel groups; and removing noises for each pixel group in the image according to a corresponding noise model to obtain the scanned image with better quality and/or contrast. A system for filtering noises in an image scanned by charged particles is also disclosed.
