Method and system arranged for filtering an image

A system arranged to filter an image, the system comprising:

• a memory unit arranged to receive image data wherein the image comprises a plurality of pixels;
• a image region definer arranged to define, for each image pixel out of multiple image pixels, an image region;
• a spectral analyzer arranged to
• divide a frequency spectrum of each image region into at least three image region frequency range components, and
• calculate an energy level for each of the image region frequency range component;
• a comparator configured to compare the energy level of each image region frequency range component to at least one frequency region threshold to provide a comparison result for each image region frequency range component, 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 image region frequency range component, said determining based on a comparison result associated with the image region frequency range component and based on a configurable decision rule, wherein the processing operation is selected from a filtering operation and a bypass operation;
• and
• an image processor arranged to process each image region frequency range component according to the determination to provide processed image data and send display instructions, based on the processed image data, that cause the display to display the processed image data.
