Abstract

There is disclosed a method and apparatus for generating a depth map and 3D video. The method of generating a depth map operates on two frames in a 2D video stream. The method comprises estimating a global motion vector and block motion vectors for the first frame and projecting the block motion vectors onto the global motion vector to obtain correlation parameters. A metric is calculated for the number of static blocks in the first frame. Then the background is determined to be static or dynamic in accordance with the motion vectors, the number of static blocks and the correlation parameters. Finally, a binary depth map is computed in accordance with the motion vectors, the number of static blocks, the correlation parameters and the determination of whether the background is static or dynamic.
