Example Sentences:

1.

The main works are as follows : firstly , we compare image enhancement in wavelet domain with that based on unsharp masking and indicate that there is intrinsic relation between them , namely they both enhance images by enhancing the high frequency coefficients . because after an image is decomposed in wavelet domain , every high frequency can be enhanced . however , if unshrap masking is used , only one high frequency channel is enhanced 本文主要研究了基于小波多分辨分析的图像去噪和增强，主要工作如下： 1将反锐化掩模与基于小波多分辨分析的图像增强进行了对比分析，指出它们之间存在着内在的联系，即两者都是对与图像边缘细节对应的高频实行增强，而且指出前者只不过是后者的一个特例，因为小波分解后，多级尺度多个高频通道可得到增，而反锐化掩模仅增强了一个高频通道。
