一种TM遥感影像的分割算法

Study on a Segmentation Algorithm for TM Remote Sensing Image

从多分辨率分析角度分析图像分割概念，研究已有的图像分割方法，阐述基于二进小波变换的多分辨率分析原理，采取由粗到细的控制策略，有效地选取最优分割阈值，从而实现对TM遥感影像的分割，实验结果表明该算法对复杂遥感影像分割是有效的。

Based on the multi-resolution analysis theorem,the image segmentation concept is analyzeu and the image segmentation methods are studied. The image segmentation problems are described with the theorem of multi-resolution analysis based on dyadic wavelet transformation, according to the tactics from coarse to re- fined, the best threshold to segment the original image effectively is chosen, and finally the TM remote sensing image is segmented. The experimental results indicate that the algorithm is valid for the segmentation of complicated remote sensing images.
