摘要： The present invention involves detecting dark noise artifacts in coded images and video. Locations of artifacts in compressed pictures are found. A strength of the artifact per block is determined as is an overall dark noise artifact strength for each picture. Artifact detection and strength assignment is performed by analyzing candidate areas that could be prone to this type of artifact. Multiple features such as block variance, color information, luminance levels and location of the artifact could be used in this process. Also, median filtering may be used on the identified areas to eliminate isolated areas. A final artifact parameter for each picture can be assessed based on the total number of blocks that are classified as dark noise and also the strength of each macroblock.

摘要： The present principles relate to a hypothetical reference decoder (HRD) for a Scalable Video Coding extension for a compression algorithm. One such implementation proposes to modify the H.264/AVC HRD for use with the SVC of AVC. That implementation defines HRD constraints for each interoperability point of SVC. One implementation in particular is described, but other implementations are possible and are contemplated by the present principles. The changes for spatial, temporal, and SNR scalability are shown. There are also changes to the related HRD parameters followed that are shown. The several mentioned implementations provide rules for an HRD for SVC. At least one implementation proposes the SVC-HRD rules as modifications to the AVC-HRD rules. A user may use the proposed SVC-HRD rules to build an SVC-HRD and test a bitstream for SVC compliance.

摘要： A method and apparatus for detecting banding artifacts in digital images and video contents. The method operates to (i) find the locations of the banding artifacts, (ii) determine the strength of the banding artifact per block, and (iii) determine overall banding artifact strength per picture. The banding artifact detection and strength assignment is done by first finding areas that are prone to banding artifact and then considering the local characteristics of the area to reduce the false detection. The banding artifact strength of a picture is determined by considering the size and the strength of the artifact areas in this picture as well as the artifact strength in the neighboring pictures.

摘要： There are provided methods and apparatus for stereoscopic video coding using scalable video coding. A scalable video encoder includes an encoder (100) for encoding at least two views corresponding to multi-view video content by, encoding a particular view of the at least two views as a base layer, and encoding each of at least one other view of the at least two views as an enhancement layer using a prediction from a lower layer corresponding to at least one of the particular view and the at least one other view. The at least two views are encoded based on a selection from among at least two of temporal, spatial, and signal to noise ratio scalability techniques.
