| 摘 要： | 研究了在连续的X波段导航雷达图像序列中丢失一帧图像状态下的一种快速修复算法.该算法主要采用基于运动估计与运动补偿的视频序列修复技术进行插帧修复.具体步骤是根据雷达图像中像素点的运动特点,采用改进的三步搜索算法并结合双向运动估计进行搜索,然后对矢量场进行后续处理,最后内插出重建帧.为了提高图像修复的精度,还引入了亚像素运...

| Abstract: | A method of image restoration for a lost frame in nautical radar image sequence is proposed,which is based on the motion estimation and motion compensation of image sequence restoration technology.According to the characteristics of the radar image pixel motion,a improved three-step motion search algorithm combined with bi-direction motion estimation is developed.The vector field is then processed.Thus,the lost image could be reconstructed finally.In order to improve the accuracy of image restoration,the su... |
