Benefits of technology

[0007]According to an aspect of the present invention, there is provided a video encoder. The video encoder includes an encoder for encoding a picture by enabling color compensation of at least one color component in a prediction of the

Problems solved by technology

In those multi-view applications, a very large amount of video data is often involved.
This leads to differences in luminance and chrominance when the same parts of a scene are viewed with different cameras.
Under these scenarios, luminance and

Embodiment Construction

[0018]The present invention is directed to methods and apparatus for illumination compensation and color compensation for Multi-view Video Coding (MVC). The color compensation may be applied to at least one color component.

[0019]Advantageously, embodiments of the present invention provide improved coding compression of simulcast multi-view data. As used herein, a multi-view sequence is a set of two or more video sequences that capture the same scene from different view points. It is to be appreciated that the teachings of illumination compensation and color compensation as disclosed herein may be used jointly or separately in various embodiments of the present principles, while maintaining the scope of the present principles.

[0020]The present description illustrates the principles of the present invention. It will thus be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles o

Abstract

There are provided a method and apparatus for illumination and color compensation for multi-view video coding. A video encoder includes an encoder (100) for encoding a picture by enabling color compensation of at least one color component in prediction of the picture based upon a correlation factor relating to color data between the picture and another picture. The picture and the other picture have different view points and both corresponding to multi-view content for a same or similar scene.
