Efficient Motion Estimation for Video Coding Using Depth Information
Soon-kak Kwon · IOSR Journal of Engineering · 2013
This paper presents the reducing method of the complexity in motion estimation for video coding by using the depth information.We obtain two regions of each picture within video sequence from distance information calculated by depth camera.Background region has large distance, but object region has small distance.If a current block is the object region, then motion is searched within the object region of reference picture.Also if a current block is the background region, then motion is searched within the background region of reference picture.From simulation results, we can see that the proposed method compared to the full search method remains the almost same as the motion estimated difference signal and significantly reduces the searching complexity.
