Abstract
Methods of filtering random noise and salt and pepper noise that minimize a loss of detail in an image are described. Sample values of an image that are within a tolerance within a sliding window are used to normalize a sample centered in the sliding window to filter random noise and minimize a loss of detail in an image. Sample values of an image in a sliding window are sorted into a sorted array, and mapped to values based on pre-defined regions of the sorted array to filter salt and pepper noise and minimize a loss of detail in an image.
