基于阈值与边缘的高分辨率影像阴影检测方法

基于基础的阈值分割方法,结合特殊的灰度增强方法和灰度形态学运算,提出了一种检测高分辨率卫星影像阴影方法,并以上海市中心城区的QuickBird影像为例进行实验,对结果进行分类区域评价,同时证明了该方法的实用性。

High-resolution image shadow detection method based on threshold value and edge

A high-resolution satellite image shadow detection method was proposed in the thesis base on the basic threshold segmentation method and combining with specific gray enhancement method and gray morphology calculation.The experiments were done by taking the QuickBird image in center of the city of Shanghai as an example,and a classification regional evaluation was done to the results of the experiments,meanwhile,the practicability of this method was proved.
