[Paper] Quality Estimation Method for Fractal Compressed Images

抄録

A method for estimating the quality of images compressed by fractal image compression is presented in this paper. Fractal image compression based on an iterated function system is one of the compression techniques for digital images. It utilizes the self-similarity of images and achieves high image-compression performance. However, fractal image compression is currently not being in widespread use because it does not necessarily provide high-quality compressed images. We cannot determine whether a given image is unsuitable for fractal image compression without encoding it. Therefore, in this paper, we propose a new criterion for estimating the suitability of fractal image compression for a given image. By using the proposed criterion, we can estimate the quality of the compressed image in a short time without actually encoding the image.
