Abstract
In an image enhancement method, computer program product, and system a set of boundary frequencies within a frequency spectrum are defined. The boundary frequencies divide the spectrum into a plurality of different spatial frequency regions. A digital image is then processed with a filter having a plurality of functions. Each function is exclusive to one of the spatial frequency regions. The functions of adjoining regions have equal values at respective boundary frequencies. A set of peak and or valley filter values of the functions at the respective boundary frequencies can be defined.
