Abstract : A new method for image magnification using fractal based technique is proposed. We call this new technique fractal image magnification. The technique is designed assuming the self transformability property of images. The technique described here also utilizes Genetic Algorithm with elitist model that greatly decreases the search for finding the self similarities in the given image. The article presents theory and implementation of the proposed method. A simple distortion measure scheme is also proposed to judge the image quality of the magnified image. Comparison with one of the most popular magnification techniques the nearest neighbor technique, is made.
