An approach has been proposed for automatic adaptive subtitle coloring using fuzzy logic-based algorithm. This system changes\r\nthe color of the video subtitle/caption to ââ?¬Å?pleasantââ?¬Â color according to color harmony and the visual perception of the image\r\nbackground colors. In the fuzzy analyzer unit, using RGB histograms of background image, the R, G, and B values for the color\r\nof the subtitle/caption are computed using fixed fuzzy IF-THEN rules fully driven from the color harmony theories to satisfy\r\ncomplementary color and subtitle-background color harmony conditions. A real-time hardware structure has been proposed for\r\nimplementation of the front-end processing unit as well as the fuzzy analyzer unit.
