A CRUCIAL PART OF A SUCCESSFUL MACHINE VISION APPLICATION IS SCENE CONTRAST. COLOR CAMERAS CAN DELIVER THE REQUIRED CONTRAST IN SOME APPLICATIONS WHERE MONOCHROME CAMERAS FAIL. THE THREE DIMENSIONAL RED, GREEN, AND BLUE (RGB) PIXEL COLOR DATA PROVIDES THE CONTRAST, BUT IS COSTLY AND COMPLICATED TO PROCESS, FREQUENTLY REQUIRING NONSTANDARD COLOR PROCESSING ALGORITHMS. ON THE OTHER HAND, THREE ONE-DIMENSIONAL METRICS HUE, SATURATION, AND INTENSITY (HSI) EXTRACTED FROM A COLOR IMAGE CAN BE ANALYZED WITH CONVENTIONAL MONOCHROME IMAGE PROCESSING TECHNIQUES. A STAND-ALONE RGB TO HSI CONVERSION BOX IS APPLIED TO A VARIETY OF COLOR VISION APPLICATIONS TO ILLUSTRATE THIS TECHNIQUE. OFTEN A SINGLE CHANNEL OF THE HSI TRIPLET IS SUFFICIENT FOR MANY APPLICATIONS, THEREBY REDUCING PROCESSING TIME AND COMPLEXITY. IN THESE CASES PROVEN MONOCHROME IMAGE PROCESSING SYSTEMS CAN BE APPLIED.
