System and method for isolating near achromatic pixels of a digital image

A method for isolating near achromatic pixels of a digital image comprising the steps of:

• receiving image data encoded as a plurality of pixels, each pixel having component values in a multi-dimensional color space;
• extracting chroma data from pixels of received image data;
• calculating histogram data from extracted chroma data;
• determining an adapted threshold value from extracted histogram data;
• comparing a determined adapted threshold value to component values of the plurality of pixels;
• and
• isolating pixels as near achromatic in accordance with an output of the comparison of the determined adapted threshold to component values.
