海量遥感图像频域编辑器软件的设计与实现

Design and Implementation of Remote Sensing Image Frequency Editor

针对图像增强和图像复原中变换算法的问题,该文设计和实现了海量遥感图像频率域信息编辑的软件构架。采用该软件,不仅能高效地显示图像的频率信息,而且同时提供了Barlett低通滤波器、Gaussian高通滤波器等基本滤波工具,使得可视化交互式滤波器设计成为可能,从而达到对频率信息进行编辑修改的目的。利用这一工具,设计和实现了TM影像周期条带噪声去除的滤波器。实验结果证实了该软件构架的可行性。

Aiming at problems of image transform in image enhancement and image restoration, this paper presents the design and implementation of a software tool for modifying huge remote sensing image frequency information. With the tool, frequency information as well as visualize frequency information are edited. Such standard filters as Barlett low-pass filter and Gaussian high-pass filter are supplied. The tool＇s usefulness by designing a filter for periodic noise removal is demonstrated. The experiment with TM images shows the tool is efficient.
