Stereo image coding: State of the art

3D imaging recently has attracted great attention from industries and research institutes, this is due to the novelty and the impression of depth generated by the exploitation of the stereovision phenomenon. Stereovision consists to exploit two images (left and right) of the same scene captured from different viewpoints, this pair of images is used to reconstruct the relief of the scene. Since, such a pair of images provides a large amount of data to be stored or transmitted, hence efficient compression techniques are essential for handling this type of images. This paper aims to make a complete review of all the most prevalent works in the literature for encoding stereoscopic images.
