| Abstract: | Fractal interpolation and wavelet transformation are widely used in digital image processing. A method of image magnification according to the properties of fractal interpolation and wavelet transformation are presented. The experimental results show that the method has better performance than the other methods with choosing appropriate wavelets, for retaining image texture and intensifying image edge |
