| 20100208800 | METHOD AND DECODER FOR DECODING AN IMAGE FRAME OF AN IMAGE FRAME SEQUENCE - The invention is related to a method for decoding an image frame of an image frame sequence and to a corresponding decoder. The method comprises the steps of reconstructing a representation of the image frame, classifying at least one block boundary as to be either high-freq or low-freq and filtering pixels of the at least one block boundary in dependency on the classification and outputting the filtered representation. Film grain noise and/or random texture are more likely to produce high-freq boundaries. Therefore, filtering boundary pixels in dependency on frequency classification helps preserving film grain noise and random texture which are of relevance for video quality at high bit rates. | 08-19-2010 |
| 20110058608 | Method and apparatus for image encoding using hold-MBs, and method and apparatus for image decoding using hold-MBs - In video/image coding, macroblocks (MBs) are often intra coded in raster scan order, starting from one seed MB. The invention improves intra prediction for optimized usage of multi-core processors. Encoding starts from multiple intra coded seed MBs per frame, and continues with adjacent MBs. A predefined prediction spread pattern (growth pattern) is used that comprises simultaneous prediction of two or more adjacent MBs per MB. Adjacent MBs with high coding cost are called “Hold-MB” and can be held from being processed, until another neighbouring edge is available for prediction. Encoding comprises marking a MB with high coding cost for deferred prediction. This MB is skipped while the other MBs are encoded. When a further adjacent MB was encoded, the marked MB is predicted based on the adjacent MBs. Since a decoder receives the deferment marks and uses the same growth pattern, it follows the encoder, and predicts and decodes correctly. | 03-10-2011 |
