A method performed by a software process executing on a computer system, includes accessing a digital image having a plurality of pixels encoded in a color space that defines hue as a pair of Cartesian coordinates. The method also includes calculating a chroma value for a specified pixel by determining a distance between a point corresponding to a hue coordinate pair value for the specified pixel and a Cartesian origin point. The calculated chroma value is compared to a predetermined threshold and an image processing operation is performed on the digital image based on a result of the comparison.
