Depth map coding

摘要

The invention relates to coding of depth information for multi-view video coding. Different parameters and/or any features from picture encoding or the encoded and reconstructed pictures may be used in the coding of the depth information, especially in filtering the depth picture using e.g. a loop filter in the depth coding loop. The same principle may be applied in decoding, that is, the decoded (texture) pictures and parameters may be used to control the decoding of the depth data, e.g. to control the filtering of the depth data in a loop filter. Parameters and data that may be used as such control may comprise features extracted from the reconstructed pictures, the encoded video data and parameters, the motion estimation data and others.

1. A method for encoding picture data, the method comprising:
encoding at least one texture element of said picture data to obtain at least one encoded texture element, forming at least one texture encoding parameter in said encoding, encoding at least one depth element associated with said at least one texture element to obtain at least one encoded depth element, applying filtering to depth data in said encoding of at least one depth element, wherein the filtering is loop filtering, and controlling said filtering using said at least one texture encoding parameter.
