Benefits of technology

[0007]Therefore, an object of the present invention is to provide a method for image prediction of a multi-view video codec capable of improving coding efficiency, and a computer readable recording medium therefor.
[0008]Another object of the present invention is to provide a method for image prediction of a multi-view video codec capable of effectively using images of multiple different views, and a computer readable recording medium therefor.

Problems solved by technology

In actuality, there is almost no technique that uses the inter-view correlation.
However, the related art multi-view video codec performs coding by using an image of a different view simply as a reference image, failing to perform inter-view motion compensation in due consideration of a disparity, which is a displacement value between views.
Thus, improvement of coding efficiency is limited because no technique is used for removing inter-view redundancy between images.

Embodiment Construction

[0018]In a codec that supports multi-view, prediction can be performed based on images of multiple different views, besides using a technique employed in the related-art two-dimensional codec. The prediction based on images of multiple different views must be concerned with how to obtain the most similar image to an image of a view to be currently compressed, using multiple images of different views. Even if a multi-view codec (MVC) is also a codec that supports multi-view, a technique using images having multiple different views has not yet been employed therein. For this reason, a technique for effectively compressing an image of a view to be currently compressed, based on images of different views will be described according to embodiments of the present invention.

[0019]A method for image prediction of a multi-view video codec according to exemplary embodiments of the present invention can be realized as programs and stored in a computer-readable recording medium that can execute...

Abstract

Provided are a method for image prediction of a multi-view video codec capable of improving coding efficiency, and a computer readable recording medium therefor. The method for image prediction of a multi-view video codec includes partitioning an image to a plurality of base blocks, acquiring information of reference images which are temporally different, acquiring information of reference images which have different views, and predicting a target block based on the acquired information. Accordingly, an image that is most similar to an image of a view to be currently compressed is generated using multiple images of different views, so that coding efficiency can be improved.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application Nos. 60 / 884,495 and 60 / 886,759, filed on Jan. 11, 2007 and Jan. 26, 2007, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure relates to multi-view video coding, and more particularly, to a method for image prediction of a multi-view video codec and a computer readable recording medium therefore.[0004]2. Description of the Related Art[0005]A multi-view video codec is a video codec that outputs a plurality of images captured from different views as one or multiple compressed bitstreams. The multi-view video codec performs compression using a correlation between different views, i.e., inter-view correlation, as well as compression using spatial / temporal correlations, which is one of characteristics of a related-art video codec. In the multi-view v...
