摘要：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 spacethat defines hue as a pair of Cartesian coordinates. The method also includes calculatinga 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 originpoint. The calculated chroma value is compared to a predetermined threshold and animage processing operation is performed on the digital image based on a result of thecomparison.
