摘要
遥感图像的条纹噪音,不但影响图像的判读,而且对图像的后续处理影响较大。利用常规处理软件去噪,在去除条纹的同时,也去除了图像的细节纹理,相当于降低了图像的几何分辨率;使用小波阈值去噪方法,效果欠佳。文章使用小波反阈值方法,不仅去除了图像上的条纹噪音,而且对图像的细节纹理不产生目视效果上的影响,达到了较好的效果。
Stripe noise of remote sensing image has influence not only on image interpretation, but also on following processing. Using conventional processing software to removing stripes, detail texture of images can be removed, and geometrical resolution of images is also reduced. It is not effective to de - noise by wavelet threshold method. Wavelet counter - threshold method is used to remove stripes. This effective method can not only remove stripe noise of images, but also has not any visual influence on detail texture of images.
