Object motion description in stereoscopic videos

The efficient search and retrieval of the increasing volume of stereoscopic videos drives the need for the semantic description of its content. The derivation of disparity (depth) information from stereoscopic content allows the extraction of semantic information that is inherent to 3D. The purpose of this paper is to propose algorithms for semantically characterizing the motion of an object or groups of objects along any of the X, Y, Z axes. Experimental results are also provided.
