摘　　要：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。阐述了运动模糊图像的退化模型和复原模型,利用二值图的信息来估计模糊方向,通过对二值图的矩阵变换来估计模糊尺度,再利用约束最小二乘方滤波的方法复原图像。实验表明,该方法行之有效。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. The degradation model and the recovery model were described. The blurring direction was estimated with binary image information; the blurring degree was estimated with matrix transformation of the binary image; constrained least square was applied to recover the image. The result of experiment and simulation showed that the method was feasible.
