Abstract(in English) | In the fractal image coding, it is significant to determine a suitable contractive mapping, because the mapping has a serious influence on reconstructed images. The traditional fractal image coding methods determine it by minimizing the error (collage error) between an original image and an image obtained by once applying the mapping to the original. Therefore, minimizing the collage error dose not correspond to minimizing the error between the original image and the reconstructed image, that is the image obtained by decoding in the fractal image coding. Hence, in order to obtain the high-accuracy reconstructed image, we propose a new criterion-based method by using GA and SA to determine suitable IFS parameters that represent the best contractive mapping. The proposed method always provide better reconstructed images than the other conventional methods. |
