基于视频重建的颤振探测与图像复原方法

Motion Detection and Image Restoration Based on Video Reconstruction from a Single Coded Exposure Photograph

提出了一种基于单次曝光视频重建的颤振探测与图像去模糊的方法,该方法对采样区域处的像素进行编码曝光,并由此重建出一系列视频图像,通过视频图像的位移矢量构建点扩展函数,最终复原模糊图像。该方法不需要额外硬件,在系统复杂度和成本上有着一定优势。仿真结果表明,该方法可以较好地复原图像。

A motion detection and image restoration method based on video reconstruction from a single coded exposure photograph is proposed. The exposure time of each pixel in the sampling regions is modulated respectively, and a serial of video frames are reconstructed from the coded exposure image of each region. By using the frames of the videos, displacement vectors and point spread function are calculated, and used to restore the blurred image finally. The proposed approach needs no additional devices and has advantages in both systematic complexity and cost. The effectiveness of the proposed method is experimentally confirmed by the results of simulation on problems of motion detection and image restoration.
