growing fast and getting increasingly important. However, some problems may occur during the production of stereoscopic contents, such as the determination of stereo bases for scenes of different depths, false parallax, and the synchronization of two video sequences captured from two independent cameras. This thesis addresses on how to synchronize the left-eye-view and right-eye-view video sequences which are not synchronized for healthy and comfortable viewing of stereoscopic videos. The research involves the development of a coarse-to-fine algorithm that employs the motion field information for finding the trajectory correspondence between two sequences to be synchronized. In the algorithm, motion fields are obtained by means of full-search block matching motion estimation. Through a hierarchical search of similar motion field information, the trajectory correspondence can be found in low computational
complexity. Simulation results indicate that the proposed algorithm is able to
synchronize stereo video sequences of various types in a short latency of time.
