摘要
遥感图像处理对于航空、航天、军事侦察、灾害预报等许多军事和民用领域至关重要,本文针对遥感图像的特点,提出了一种基于小波变换的图像边缘检测方法,同时还对小波变换在图像处理中的适用性进行了详细分析。由实验结果表明,本文方法可以获得非常细致有效的边缘信息,在有效抑制噪声的同时,提高了边缘定位精度。
Remotesensing image processing is very important on many military or civil applications,including aviation, aerospace,spying and disaster forecasting.In this paper, we provided a new edge detection algorithm based on wavelet transform method toward applications on remote sensing. At the same time, we analyzed the adaptation for wavelet in image processing. From experiments,the algorithm can get effective edge information, and improve edgelocation precision while restraining noise efficiently.
