Computer stereo vision is the extraction of 3D information from digital images, such as those obtained by a CCD camera. By comparing information about a scene from two vantage points, 3D information can be extracted by examining the relative positions of objects in the two panels. This is similar to the biological process Stereopsis . Stereoscopic images are often stored as MPO (multi picture object) files. Recently, researchers pushed to develop methods to reduce the storage needed for these files in order to maintain the high quality of the stereo image .
