Abstract
Methods and systems related to the detection of 3-D video content are disclosed herein. Specifically, a video image file may be analyzed in order to determine if it contains 3-D stereoscopic video content. An assumption is made regarding the possible 3-D format of the video image file. The assumption could be that the video frame includes a left portion and a right portion where each portion contains respective stereoscopic image perspectives. Image analysis algorithms could be used to determine if the left and right portions are sufficiently similar to confirm the assumption. If so, an indication could be carried out that could include a change to metadata or a similar change to associated video image file information. If the left and right portions of the video frame are not sufficiently similar, another analysis may be performed to test a different 3-D file format assumption.
