Color look-up space based natural color fusion algorithm and DSP real-time implementation

Color look-up space based natural color fusion algorithm is a fast and efficient algorithm that applies the color of natural reference image to multiband fusion image. The color mapping is derived from the combination of a multiband image and a corresponding natural color reference image in different environment and different observeing task that improve situational awareness and reduce action times. For various potential application, a specific real-time harfware and software were designed. The target processor was a Texas Instruments TMS320DM642 fix point DSP. PAL video was captured, processed, and displayed on a standard monitor. The framework of color look-up space based natural color fusion algorithm was discussed. The design of hardware and software of 2-dimensions color look-up table was analysised. The optimizations used to achieve real-time performance was analysised as well as future plans of hardware design, system design and application.
