摘要
针对数码相机获得的模糊图像,分析了图像产生缺陷的主要原因,以信息光学中的传递函数为基础,建立了其中三类常见失真图像对应的模型,并在MATLAB平台上设计出了相应的修复软件.
The main reasons for distortion in image output of digital cameras are firstly analyzed. With the adoption of the transfer functions in information optics, models of three common distortions are set up. Finally, a computer processing program based on MATLAB is developed for restoration.
