SAR图像边缘的小波抽取算法研究

随着地球物理勘探、航空摄影、卫星监测技术的发展，人们获得的各种图像资料也与日俱增。如何从众多的图像资料中快速获取所需的信息是一个引起广泛兴趣的问题。实现图像信息的自动识别技术是解决问题的途径之一。本文就是在作为图像自动识别技术中必不可少的一个环节———图像边缘抽取领域中，针对小波分析在具体的合成孔径雷达（ＳＡＲ）图像处理中的应用前景进行了研究工作，并取得了一些结论。

RESEARCH ON SAR IMAGE EDGE EXTRACTING ALGORITHM BASED ON WT

With the development of geophysical exploration, aerospace photographing and satellite surveillance technology, the amount of acquired image data has increased sharply. How to extract useful information from the vast amount of image data is an important subject which has arisen widespread interest. One of the possible solutions is to develop automatic image recognition technology. This paper, focusing on the field of image edge extraction that is an indispensable step in the auto recognition technology, introduces some research work which have been done with the application of WT in SAR image processing. Some conclusions are also presented in this paper.
