Performance Comparison of the Color Coordinate Systems Applied on Satellite Images

Yas Abbas Al-Sultanny    

Abstract: The Spot and Landsat satellite images carrying a lot of information, therefore the processing of these images controlled by two important parameters, the time and the performance of the processing. In this research the different types of color coordinates models are tested on the spot satellite images, to compare the performance of the two parameters. The algorithms of color coordinate transformation tested on satellite images of different sizes and types, by converting the color images from the basic RGB model to LHS, HIS, YIQ, HSV, CMY, principle component transformation (PC) and vise versa. The results shows that the YIQ model takes the smallest time than the other models, and the RGb model takes longer time, and becomes unpractical for satellite images of big size, the principle component will be more effective in multi-band satellite images (spot of 3 bands, Landsat of 7 bands), since the process will be applied to only one band, not to all the bands, in this case the transformation work well in reducing the process time, with a less performance.
