Fractal image coding : a review : Fractals in electrical engineering

Specific classes of Fractals can be used for Digital Image Compression or Coding. For such an application, the general problem statement is the following. Given any original discrete image specified by an array of pixels, how can a computer construct a fractal image-the coded image-which is both visually close to the original one, and has a digital representation which requires fewer bits than the original image. In this paper, we describe an approach to image coding based on a fractal theory of iterated contractive transformations defined piecewise
