In this paper, a novel approach is proposed for automatic adaptive subtitle color changing based on fuzzy logic. Fuzzy analyzer, the core of this system, changes the color of the subtitle/caption to a 'pleasant' color according to color harmony and the visual perception of the image background colors. Using RGB histograms of background image, the fuzzy analyzer computes the R, G and B values for the color of the subtitle or caption based on fuzzy rules which are designed to satisfy complementary color and subtitle-background color harmony conditions.
