检测卫星遥感照片之间差别的简便方法
Simple detection of the difference between two photographs taken by satellite ERTS
摘要
本文提出一种检测两幅图象之间差别的新方法——把白光调制的斑纹图样作为光学信息处理时的无规载波.实验证明,此法也会有效地产生很高的裕量来对图象的信息编码.所得的结果与Francon等人提出的用相干光调制的斑纹图样法的结果相类似,但这里提出的方法较简便.
Abstract
A new method for detection of the difference between two images is presented. In this method, the authors regard a white light speckle pattern as a random carrier for optical processing. The experiment demonstrated that it can be used to code information of images in an efficient way yielding a high degree of redundancy. The result obtained is similar to that by Frangon’s modulated coherent light speckle patterns. But this method is simpler than Francon’s.
