摘要
通过对航空遥感影像的特性统计值进行计算,将得到的客观统计特性值与主观评价结果进行比较,来对图像的成像质量进行评价。在实现过程中采用了现在常用的图像特性统计值———信息熵、清晰度、三阶平均细节累积量,同时也利用了调制传递函数对航空遥感影像进行试验分析。在此基础上,对航空遥感数字影像进行了试验,并对试验结果进行分析、比较了利用这些特性统计值进行质量评价的效果。
This article evaluates the areophoto image quality by computing and analyzing their statistical characteristics, and compares the objective statistics characteristics with the result of subjective one to obtain some appropriate objective evaluation parameters. The common characteristic statistics parameters, such as entropy, definition, mean three-order cumulants are used in the paper. And the MTF is used to analyze aerophoto image in the experiment. Based on it, an experiment is done on some areophoto images, and their respective characteristic and evaluating results are analyzed and compared.
