摘要
数字图像质量的评价涉及到图像的信息量问题,但在光电匹配滤波相关识别中,输入目标图像的信息量大小并不是相关输出优劣的决定因素。本文着重介绍了目标图像由于不同原因可能发生各种变化,导致图像信息量也随之变化,而滤波器本身具有一些特性,使得相关输出在输入目标图像产生这些变化时呈现的结果各不相同。
The digital image quality evaluation involves the information capacity of image, but the magnitude of information capacity of input target image can＇ t determine the quality in the correlation output. This paper introduces the various changes in target image may occur due to different reasons, resulting in the change of information capacity of image, and some characteristics of filter cause different results in the correlation output with those changes in target image.
