摘要
通过对边缘和平滑区域采用不同的插值处理方法 ,能获得清晰的变换图像 对自然景观图像、医学图像和人物图像进行了变换 ,得到的结果说明了文中算法的有效性
Fractal interpolation was adopted in the algorithms of image affine transform to avoid blurring the contour and degradation of image, while edge detector is used to extract the image edge contour Different interpolation methods were applied to the edge and smooth region Several numerical results for medical and scenical image show that the algorithm is effective and simple to implement
