Effective Fractal-Based Coding of Color Image Using YIQ Model
Seongjong Kim, Joon-Mo Lee, Inchul Shin · Journal of IKEEE · 1998
Fractal-based monochrome image coding method can be easily applied for color image compression by splitting the color image into different primary spectral channels such as RGB, YIQ or , and encoding each channel independently According to this method, it needs to repeat the fractal coding for each channel, so it have the problem of encoding time. In this paper, a fractal-based coder for color still image is proposed which features the enhancement of compression rate and the reduction of coding time. As the result of the experiment where the proposed algorithm is applied far color images, the compression rate is enhanced by 28 : 1 above with average PSNR value , do not lossless encoding process using JPEG. And the encoding time is reduced by maximum 11.5 %.
