A system for detecting subsurface blood of a region of interest during a surgical procedure includes an image capture device that captures an image stream of the region of interest and a light source that illuminates the region of interest. The controller applies at least one image processing filter to the image stream, thereby decomposing the image stream into a plurality of color space frequency bands, and generating a plurality of color filtered bands from the plurality of color space frequency bands; Each band of multiple color space frequency bands is added to a corresponding band of multiple color filtered bands to generate multiple extended bands, and an extended image stream is generated from the multiple extended bands, which is surgical Displayed to the user during the procedure.
