Problems solved by technology

However, this is a static solution and not suitable for use in every situation (eg in case of mixing different 3D video contents with different formats)
[0010] There is also the disadvantage that at the receiving side, it is not known which of the two images in the composite frame is the left image and which is the right image, even if the stereoscopic format (e.g., side-by-side) of the video content to be reproduced is known. Image; sending the right image to the left eye and the left image to the right eye produces a disrupted 3D rendering of the stereoscopic image, creating an unpleasant effect for the viewer
[0012] However, this solution has the drawback of increasing the computational complexity at the transmit side and requiring the decoder to be able to infer and accurately interpret this information pattern

Abstract

A method and a system for decoding a stereoscopic video signal of the type comprising a sequence of composite frames each comprising a left image for the left eye and a right image for the right eye are disclosed. The method provides for detecting one or more edges inside at least one of the composite frames; determining a stereoscopic format of the video signal based on said edge detection; and extracting the right image and the left image based on the determined stereoscopic format.

Description

technical field [0001] The present invention relates to 3D video processing, and in particular to a method for decoding a stereoscopic video signal to display 3D video content. [0002] The invention also relates to a system for processing 3D video by implementing the aforementioned method. Background technique [0003] It is known that in order to obtain 3D effects in image or video content, the left and right eye must be presented with different images, in particular two different views of the same object (in general, an object or scene). [0004] These two images, commonly referred to as left and right images, can be generated electronically by computer graphics or can be acquired by two cameras placed in different positions and pointed at the same object. Generally, the distance between the two camera lenses is about 6 cm, ie similar to the distance between two human eyes. [0005] By displaying the left and right images at different times or with different polarizatio...
