扫描仪输出失真图像的计算机处理

On Computer Processing of Distortion Images Generated by Scanner

针对在办公自动化领域广泛应用的计算机外围图像输入设备——扫描仪,介绍了其输出图像失真的种类和产生失真的主要原因,对其中一类失真图像进行了频谱分析,并在MATLAB平台上设计出了相应的修复软件.

In the light of the fact that scanner is one kind of the most important image input peripheral equipments of computer for office automation, this paper introduces the categories of and the main reasons for distorted images from scanners, analyzes the frequency spectrum of one kind of the distortion images, and designs a computer processing program based on NMTLAB to restore some distorted images.
