| 摘 要： | 针对背景静止的立体视频提出了一种快速的基于背景重构的视频分割算法.先利用帧差法分别确定出左右视频的前景运动区域,再重构出该区域的背景图像,最后,通过视频图像和背景图像的对比来准确地提取运动前景.然后,先匹配左右图像序列的背景图像,并保存它们的匹配结果,再分别对各立体图像对的运动前景进行匹配.采用该方法将立体视频分割可以...

| Abstract: | A fast video segmentation algorithm based on background reconstruction is proposed for stereo video with static backgrounds.Firstly,the moving foreground areas are found out by the frame difference respectively.And then,the backgrounds shaded by foreground areas are reconstructed.At last,the moving foregrounds could be separated by comparing the backgrounds information with the current frame images and it could achieve the segmentation accurately.After that,two background images reconstructed from the left ... |
