一种层次化的目标表示方法

A Study on Detecting Man made Objects from Natural Background in Space Sensing Imagery

提出一种支持自底向上的目标识别策略的线画图象的表示方法。该表示建立在一种基于线→角→面的层次上，它的低层表示可以使预识别过程能够以简单的统计方法实现，高层表示支持在模型知识约束下的匹配。

An algorithm for detecting man made objects from natural background in space sensing imagery is presented by applying multi resolution analysis based on the wavelet transform and features fusion technique. Experimental results on SAR images have shown that the algorithm is effective and applicable.
