Method for forming a digital sharpening/blurring filter

摘要

A method for forming a digital sharpening/blurring filter, for use in an image processing work station, incorporating MTF functions derived from the image processing chain, comprising the steps of: a) enabling an image processing work station operator to select a filter control value from a plurality of filter control values that relate to human sharpness perception values; b) estimating the MTF function of the image processing chain; and c) forming a digital sharpening/blurring filter, which when introduced into the image processing chain, changes the overall MTF function in accordance with the selected filter control value so as to implement the operator selected change in sharpness. <IMAGE>
