摘要
介绍了基于软门限的小波分析去除遥感图像噪声的处理方法,并利用一些指标,与传统的滤波处理方法进行对比分析后发现,基于小波分析的图像滤波方法,在去除图像噪声的同时,可以很好地保持图像边缘纹理等细节信息。
This paper introduced the method of remote sensing image noise reduction based on wavelet analysis of soft thresholding. It was found that the method of wavelet-based image filter can keep the edge detail information of image while reducing remote sensing image noise after comparing with some traditional filter treatments by some indicators.
