  • Abstract Conventional fractal image coding can achieve an extremely high
    visual quality, but it requires lots of time in encoding. To solve the problem,
    the no search method has been proposed in the literature. It reduces the
    encoding time indeed, but the reconstruction quality is also reduced. By
    investigating several papers that focus on raising the quality of image, we
    propose a new method that combines the advantages of the no search
    fractal coding method and block truncation coding method. The block
    truncation coding method that focus on the detail of the image can alleviate
    the drawback of no search method which cannot work well in the detail of
    image. We also extend it to color image coding. By sharing part of the
    codes, the compression ratio can be raised further.
