摘要
提出一种利用三维场景模型对视频图像进行分析并实现图像分割的方法 .利用图像序列的前两帧获得图像的深度映像 ,实现场景的三维网格描述 .采用简单的线性算法获得运动参数 ,并对场景模型不断修正 .实验结果表明 ,这种方法有效地实现了视频分割、目标跟踪以及VOP(视频对象平面 )
An algorithm for video sequence analysis and image segmentation by using 3D scene model is presented. At the beginning of the sequence, the procedure uses two frames to acquire the depth map, and represent the scene as a 3 D wire frame computed from the depth map. A linear algorithm with low complexity is used to recover the motion parameters, and update the 3 D scene description for each additional frame. The approach ia applied to solve the problem such as video sequence segmentation, object tracking, and video object plane (VOP) generation.
