利用位相光栅彩色编码增强遥感图象中线性构造和环形构造的影象信息

ENHANCING LINEAR AND CIRCULAR STRUCTURES IN REMOTE SENSING IMAGES BY USING THE PHASE GRATING COLOR CODING

本文根据付里叶变换光学原理,对陆地卫星图象进行位相光栅编码,再在白光信息处理系统中滤波解调,使黑白图象彩色化并具有边缘增强效果。据此对吉林省中西部5幅卫片处理后,突出了线性构造和环形构造的影象信息,收到了可喜的地质解译效果。

In this paper, landsat pictures are encoded by using the phase grating according to Fourier optical transform principles and the encoded images are filtered again on the white-light information processing system. Black-white pictures are changed into colored ones and resulted in edge enhancement, after processing the five landsat pictures of the central and western areas of Jilin Province the linear and circular structures these were clearly manifested and an encouraging geologic interpretation was obtained.
