摘要
Present invention describes a method for resolution enhancement for N-view + N-depth multi-view video. Since any multi-view data contain the image of a scene at the very same time from different viewing angles; the redundant information in the neighbouring frames (spatial dimension) should be utilized to increase the resolution in each frame by using the 3D multi-view geometry and image registration techniques which uses the depth information of the views for registering the views which means warping the image on the neighbouring views. In the method described in present invention, the real (x, y, z) coordinates of the scene point X is mapped to the camera array with projection matrix Pc0 where Pc0 is a 3x4 projection matrix for camera C0. By using matrix operations, the three dimensional position of the object X (3D) can be obtained. By using obtained 3D position of the object X (3D) and the projection matrix of the camera C1 PC1, the position information of the object X (3D) for camera C1 can be obtained. The obtained position information for camera C1 with given typical 3D warping operation is the object information that falls on the camera C1. By using obtained 3D position of the object X (3D) and the projection matrix of any camera, the object information that falls on processed camera can be obtained.
