VIRTUAL VIEW IMAGE SYNTHESIS METHOD AND APPARATUS
First Claim
1. A method for processing a video signal, the method comprising:
- generating a first viewpoint intermediate picture and a second viewpoint intermediate picture by warping a first viewpoint reference picture and a second viewpoint reference picture;
determining whether a hole is present in the first viewpoint intermediate picture;
specifying a position of the hole when the hole is present in the first viewpoint intermediate picture;
obtaining a pixel value of the second viewpoint intermediate picture on the basis of the hole position; and
allocating a pixel value of the second viewpoint intermediate picture to the hole,wherein the hole is a specific region in which no pixel value is allocated to the first viewpoint intermediate picture.

Abstract
The virtual view image synthesis method according to the present invention comprises: generating an intermediate picture from a first viewpoint and an intermediate picture from a second viewpoint by swapping a reference picture from a first viewpoint and a reference picture from a second viewpoint; determining whether there is a hole in said intermediate picture from a first viewpoint; if there is a hole in said intermediate picture from a first viewpoint, obtaining the pixel value of said intermediate picture from a second viewpoint based on the location of said hole; and allocating the pixel value of said intermediate picture from a second viewpoint to said hole. A virtual picture is synthesized using a reference picture, thereby reducing the quantity of information due to encoding a virtual viewpoint picture.
