摘要
借助图像的小波变换 ,提出了一种新的图像插值方案 ,该方案利用图像小波分解后高低分辨率子带之间存在的相似性 ,由低分辨率子带插值近似高分辨率子带 ,从而得到比原图像分辨率高的图像。结合三次 B样条插值 ,实验结果令人满意。
This article propose a new image interpolation scheme by means of wavelet transform of image. After image decomposition by wavelet, the similarity between high and low resolution sub band exists. Therefore we can interpolate low resolution sub band and replace high resolution sub band, which will produce higher resolution image than the original one. B spline interpolation is also used in the scheme. The result is satisfying.
