A system for enhancing an image during a surgical procedure includes an image capture device configured to be inserted into a patient and capture an image inside the patient. The system also includes a controller that applies at least one image processing filter to the image to generate an enhanced image. The image processing filter includes a spatial decomposition filter that decomposes the image into a plurality of spatial frequency bands, a frequency filter that filters the plurality of spatial frequency bands to generate a plurality of filtered enhanced bands, and a recombination filter that generates the enhanced image to be displayed by a display.
