Abstract :
New techniques for image compression and image magnification using the theory of fractals is proposed. The fractal codes are designed assuming the self similarity property of images. In particular, to generate the fractal codes, the genetic algorithm is used which greatly decreases the search for finding self similarities in the given image. The obtained fractal codes are stored instead of the given image in the compression algorithm. Moreover the magnification task is performed using the obtained fractal codes of the image instead of the original one resulting in a reduction in memory requirement. The article presents both theory and implementation of the proposed methods. A simple distortion measure scheme is also proposed to judge the image quality of the magnified image
