摘要
分形插值和小波变换在数字图像处理中有着广泛的应用。结合分形插值和小波变换的特点,提出了一种新的图像放大方法。实验结果表明,通过选择合适的小波基,该方法与传统的图像放大方法相比,获得的放大图像的纹理特征和图像的边缘得到明显增强,并且具有更高的视觉分辨率。
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
