旋转和平移不变纹理特征的遥感影像居民地提取

本文利用Radon变换的小波系数直方图对遥感影像居民地进行提取。首先,通过Radon变换将纹理影像的旋转和平移转化为平移,然后对Radon变换后的影像进行小波变换,最后利用小波系数直方图作为旋转和平移不变特征进行纹理分割。实验结果表明:基于Radon变换的小波系数直方图方法对遥感影像居民地有较好的提取结果。

Residential area extraction from remote sensing image based on rotation and translation invariant texture feature

A remote sensing image residential area extracting method based on Radon transformation and histogram of coefficient of wavelet transform was presented in this paper.First,the texture image was translated by Radon transform to convert the rotation and translation to translation in different directions,then the wavelet transform was used for the Radon transform of texture image,and at last,the histogram of coefficient of wavelet transform was used to segment the texture as rotation and translation invariant feature.Experimental results showed that good residential area extraction results could be acquired by the method.
