遥感图像震害特征组合增强模型及其算法实现

本文在多个震例图像增强方法研究的基础上,建立了一种通过单项方法的组合实现图像增强优化的组合模型,定义了基本模型单元和模型组合型态。基于增强模型库,通过C＋＋编程实现了该算法。同时,使用1976年唐山地震后航空遥感图像对该方法进行了试验,结果表明组合模型提高了震害提取能力。

A Combinatorial Image Enhancement Model for Earthquake Disaster Assessment

On the basis of image enhancement methods in several earthquake case studies, we develop a new and optimized image enhancement model which was implemented by combining different single methods. The patterns of elementary model units and combined types of model were defined in this paper. Based on the enhancement model database, the algorithm of combinatorial model was brought out via C++ programming. Our model was tested by processing the aerial remote sensing images which obtained after 1976 Tangshan earthquake. It was proved that the definition and implementation of combined enhancement model can efficiently improve the ability and flexibility of image enhancement algorithm.
