Book Cover Image Color Reduction a Bacteria Foraging Optimization Approach

This paper aims at reducing the colors of a book cover page. This approach has mainly two steps. First is to apply an edge preserving technique and then perform the color quantization. Canny edge detector has been used to get the edge points in the text image and bacteria foraging id used to optimize the quantization. Lab color model is used to consider the visual perception of human eye. CMC distance is used as the fitness function for checking the closeness of colors.
