A system for detecting subsurface blood in 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. A controller applies at least one image processing filter to the image stream, which decomposes the image stream into a plurality of color space frequency bands, generate a plurality of color filtered bands from the plurality of color space frequency bands, adds each band in the plurality of color space frequency bands to a corresponding band in the plurality of color filtered bands to generate a plurality of augmented bands, and a reconstruction filter that generates the augmented image stream from the plurality of augmented bands, which is displayed to a user during the surgical procedure. |
