的识别奠定了基础。-A fire image color extraction algorithm. According to the color space (R, G, B) to (H, I, S) of the transformation formula and color similar to the concept of the distance, the first color image quantized to 256 colors, the color and then extracted according to the color distance. Proved that the method is simple, fast processing speed, and laid the foundation for further identification of fire image.
