The degradation model and the image restoration are introduced by the constrained least square methods including the parametric Wiener filter and the smoothing constrained least squares filter.

介绍了图像退化模型和约束最小二乘方法(包括参变维纳滤波方法和平滑约束最小平方滤波方法)。

The method of constrained least squares filter image restoration was introduced, which was applied to process image motion blur in original manuscript before the printing of electronic publishing.

根据印刷图像处理技术的基本原理，针对印前的电子出版图像处理中存在的原稿图像运动模糊现象，介绍了约束最小二乘方滤波复原技术消除图像模糊方法。
