A method and system are provided for identifying an image feature of an object (10). The system preferably includes a machine vision system (20) for capturing an original color image of the object (10) in a first color space defined by a first set of color axes to obtain a first set of image data. The first set of image data is transformed within the machine vision system (20) to a second set of image data in an optimal color space having an optimal set of color axes which define an optimal direction wherein the amount of the inter axis correlation of the second set of image data is minimized. The machine vision system (20) then manipulates the second set of image data to identify the image feature. Color differences existing in the original color image are amplified and separation between chromatically different regions of the original color image are maximized in the optimal color space. |
