摘要：
A method and a system, the system includes: a memory unit, an image region definer, a spectral analyzer, a determination module, and an image processor. The spectral analyzer is arranged to divide a frequency spectrum of each image region into at least three image region frequency range components (IRFRCs); and calculate an energy level for each IRFRC. The comparator configured to compare the energy level of each IRFRC to at least one frequency region threshold to provide a comparison result for each IRFRC; wherein each frequency region threshold is calculated based on an intensity parameter of an image section and based on an energy parameter of at least one reference image section; a determination module arranged to determine a processing operation for each IRFRC, based on a comparison result associated with the IRFRC and based on a configurable decision rule.
