摘要：We proposed high accuracy JPEG coding by including fractal image coding. JPEG coding is a commonly used standard method of accurately compressing images. However, in its decoded images, quantization errors occur especially in the region of high frequencies, such as object edges. Our method solved this problem by adding the obtained codes by fractal image coding to improve image quality in high frequency regions. Thus, our method achieved higher coding-performance than the traditional JPEG coding.
