多帧融合处理技术在运动模糊图像复原中的应用

Applying multi-frame interfusion processing to restore images blurred by motion

运动模糊图像是电视监控中常见的退化图像 ,也是图像处理和检验工作中的难题。针对电视摄像的特点 ,多帧融合处理技术从图像时间序列中提取景物的运动信息 ,构造复原滤波器 ,通过频率域反转滤波方式复原模糊图像。这项技术能够有效地增强电视监控中存在的运动模糊图像 。

Images blurred by motion are degenerative images frequently encountered in the television supervision, and cause some problems in the image processing and identification. Referring to the characteristic of the television image, multi frame interfusion processing draws the motion information from the image in time series, constructs the restoration filter, and restores images by the reversal filtering in the frequency domain. It can effectively enhance images blurred by motion in the television supervision, and is also suitable in the digital video image processing.
