摘要： Reference prediction mode values, also referred to as most probable modes or MPMs, usable for encoding or decoding of a prediction mode related to a current coding unit, are derived. By deriving three MPMs instead of two for comparison with the prediction mode of the current coding block the coding efficiency is improved. This is due to the increase in the probability that the prediction mode of the current coding block corresponds to one of the derived most probable modes.

摘要： The present invention provides a method and a device for coding and decoding at least a part of an image comprising a plurality of samples, each sample comprising at least two components, and the encoded image comprising at least one filtering parameter. The filtering comprises using at least one filtering parameter as a common filtering parameter for filtering both the first component and the second component of a reconstructed sample.

摘要： Compensation offsets are provided for a set of reconstructed samples of an image. Each sample has a sample value. A method of providing the compensation offsets comprises selecting, based on a rate distortion criterion, a classification from among a plurality of predetermined classifications. Each predetermined classification has a classification range smaller than a full range of the sample values and is made up of a plurality of classes, each defining a range of sample values within the classification range, into which class a sample is put if its sample value is within the range of the class concerned. A compensation offset is associated with each class of the selected classification for application to the sample value of each sample of the class.

摘要： The invention concerns a method, device, and computer program for motion vector prediction in scalable video encoder and decoder.
It concerns the process to determine motion information predictor in the enhancement layer of a scalable encoding scheme also known as motion derivation process. It comprises a correction of the position in the reference layer used to pick-up the more relevant motion information available due to the compression scheme. Accordingly, motion information prediction is improved.-

摘要： A method of performing sample adaptive offset (SAO) filtering on a sequence of images comprises associating a fixed set of four offset values with at least one direction of edge-type filtering. For every image area for which it is determined that edge-type filtering is to be used and for which it is determined that a direction of the edge-type filtering is said at least one direction, the fixed set of four offset values associated with said at least one direction is systematically used. Corresponding methods of generating SAO parameters and methods of encoding and decoding sequences of images are also provided.
