| 20100026887 | Method and apparatus for reversible, polynomial based image scaling - A method and apparatus are provided for reversible, polynomial based image scaling. The apparatus includes a video scaler for performing image scaling from a first base resolution image to a higher resolution image, and from the higher resolution image to a second base resolution image. The first and the second base resolution images are equal on a pixel-by-pixel basis for an entirety of the first and the second base resolution images. A scaling function used for the image scaling is based on a polynomial function having two or more degrees. | 02-04-2010 |
| 20100027897 | Method and apparatus for detecting image blocking artifacts - A method and apparatus are provided for detecting image blocking artifacts. The apparatus includes a full-reference blocking artifact detector for detecting blocking artifacts in a processed version of a picture based on a blockiness metric. The blockiness metric is determined based on respective local variations in the processed version of the picture and in an original version of the picture. | 02-04-2010 |
| 20100128789 | METHOD AND APPARATUS FOR PROCESSING VIDEO SEQUENCES - A method for processing a video sequence having a plurality of frames includes the steps of: extracting features from each of the frames, determining correspondences between the extracted features from two of the frames, estimating motion in the video sequence based on the determined correspondences, generating a background mosaic for the video sequence based on the estimated motion, and performing foreground-background segmentation on each of the frames based on the background mosaic. | 05-27-2010 |
| 20110096839 | METHODS AND APPARATUS FOR VIDEO CODING AND DECORING WITH REDUCED BIT-DEPTH UPDATE MODE AND REDUCED CHROMA SAMPLING UPDATE MODE - Methods and apparatus are provided for video coding and decoding with reduced bit-depth update mode and reduced chroma sampling update mode. An apparatus includes an encoder for encoding at least a portion of a picture using at least one of a reduced bit-depth update mode and a reduced chroma sampling update mode that respectively reduces at least one of a bit-depth and a chroma sampling of a residue signal corresponding to the portion. | 04-28-2011 |
| 20110103464 | Methods and Apparatus for Locally Adaptive Filtering for Motion Compensation Interpolation and Reference Picture Filtering - Methods and apparatus are provided for locally adaptive filtering for motion compensation interpolation and reference picture filtering. An apparatus includes an encoder for encoding picture data. The encoder includes at least one locally adaptive filter for performing locally adaptive filtering for at least one of reference picture filtering and interpolation filtering with respect to the picture data. | 05-05-2011 |
| 20110158320 | METHODS AND APPARATUS FOR PREDICTION REFINEMENT USING IMPLICIT MOTION PREDICTIONS - Methods and apparatus are provided for prediction refinement using implicit motion prediction. An apparatus includes an encoder for encoding an image block using explicit motion prediction to generate a coarse prediction for the image block and using implicit motion prediction to refine the coarse prediction. | 06-30-2011 |
| 20110170615 | METHODS AND APPARATUS FOR VIDEO IMAGING PRUNING - Methods and apparatus are provided for video image pruning. An apparatus includes a data pruner for pre-processing a picture prior to, and in preparation for, compression by encoding. The data pruner selectively removes, in the spatial domain, at least one region within the picture. At the decoder end, an apparatus includes a data restorer for receiving a decompressed picture subsequent to decompression by decoding, and post-processing the decompressed picture by selectively restoring, in the spatial domain, at least one region in the decompressed picture based on information indicating a removal of the at least one region prior to a previously performed encoding process. | 07-14-2011 |
| 20110222597 | METHOD AND APPARATUS FOR SPARSITY-BASED DE-ARTIFACT FILTERING FOR VIDEO ENCODING AND DECODING - Methods and apparatus are provided for sparsity-based de-artifact filtering for video encoding and decoding. An apparatus includes an encoder ( | 09-15-2011 |
