De-screen的实现及应用

De-screen's Implementation and It's Application

针对扫描后的数字图像有网点和网纹的问题,提出一种De-screen处理的新方法,通过去除孤立点、高斯低通滤波等方式增强图像。实验表明这种方法可以很好地去除网点、平滑网纹、保存图像细节。

This paper puts forward a new method to de-screen on digital image.This method enhances the quality of the image by replacing the isolated points and smoothing the Moiréfringe in the image since there are both isolated points and Moiréfringe in the half toned image.The experiment results make clear that this method can remove the isolated points,smooth the Moiréfringe well and keep the details of the image ideally.
