METHOD FOR PREDICTING INTER-VIEW MOTION AND METHOD FOR DETERMINING INTERVIEW MERGE CANDIDATES IN 3D VIDEO
In a method for predicting motion in a 3D multi-view video, when inter-view motion in predicting in the 3D multi-view video, a prediction motion vector with respect to a current view picture is calculated by using a motion parameter of one inter-view picture from a plurality of inter-view pictures that have been previously encoded, in order to calculate the prediction motion vector of the current view picture. As a result, complexity can be reduced by simplifying inter-view motion prediction.
1 . A method for predicting inter-view motion in a 3D multi-view video, wherein in the case of performing inter-view motion prediction of a 3D multi-view video, a prediction motion vector with respect to a current view picture is calculated by a motion parameter of one inter-view picture among a plurality of inter-view pictures that have been previously encoded in order to calculate a prediction motion vector for the current view picture.
2 . The method of claim 1 , wherein one inter-view picture is any one view picture among view pictures before the current view.
3 . The method of claim 2 , wherein one inter-view picture is a view picture just before the current view picture.
4 . The method of claim 3 , wherein the view picture just before the current view picture is a picture which is encoded temporally earlier than the current view and included in a reference picture list List 0.
5 . The method of claim 1 , wherein the prediction motion vector with respect to the current view picture is calculated by using a motion parameter of a corresponding block of a view picture just before the current view among all inter-view pictures that are encoded earlier than the current view.
6 . The method of claim 1 , wherein the prediction motion vector with respect to the current view picture is calculated by using a motion parameter of one inter-view picture among a plurality of inter-view pictures that are previously encoded and a motion parameter of a neighboring block of a current block of the current view picture.
7 . The method of claim 1 , wherein the prediction motion vector with respect to the current view picture is calculated by using a motion parameter of one inter-view picture among a plurality of inter-view pictures that are encoded and a motion parameter of at least one neighboring block of a current block of the current view picture.
8 . A method for determining inter-view merge candidates in a 3D multi-view video, wherein during inter-view motion prediction in the 3D multi-view video, in the case of calculating inter-view merge candidates of a current view picture, the same motion parameter as a motion parameter of a corresponding block in a temporal direction is used as the Inter-view merge candidates.
9 . The method of claim 8 , wherein in the case of performing inter-view motion prediction of the 3D multi-view video, a prediction motion vector with respect to the current view picture is calculated by a motion parameter of at least one inter-view picture among a plurality of inter-view pictures that have been previously encoded in order to calculate a prediction motion vector for a current view picture.
10 . The method of claim 9 , wherein one inter-view picture is any one view picture among view pictures before the current view.
11 . The method of claim 10 , wherein one inter-view picture is any one view picture just before the current view picture.
12 . The method of claim 11 , wherein the view picture just before the current view picture is a picture which is encoded temporally earlier than the current view and included in a reference picture list List 0.
13 . The method of claim 8 , wherein during inter-view motion prediction in the 3D multi-view video, in the case of calculating inter-view merge candidates of a current view picture, the same motion parameter as a motion parameter of a corresponding block in a temporal direction and a motion parameter of at least one neighboring block of a current block of the current view are used as the inter-view merge candidates of the current block of the current view picture.
