20120299911 | METHOD AND ARRANGEMENT FOR IMPROVED IMAGE MATCHING - A method and device for determining at least one set of matching attributes between a plurality of images is disclosed. Two dimensional images are projected to a three dimensional space then searched for matching attributes. Searching for corresponding attributes is much easier and computationally less intensive in the 3D space compared to a search in the 2D space. The method includes steps of projecting at least part of the images of said plurality to a 3-dimensional space resulting in a plurality of 3-D projected images (image | 11-29-2012 |
20120307017 | METHOD AND SYSTEMS FOR OBTAINING AN IMPROVED STEREO IMAGE OF AN OBJECT - A method for obtaining an improved depth precision for a stereo image of an object of interest is disclosed, comprising:

20130293787 | Fast Channel Switching - A method, a coding format and a device is provided for switching from a first data channel to a second data channel of a digital television system. At least the second data channel is coded in a multilayer scalable video coding format comprising a base layer and at least one enhancement layer. The multilayer coding is used for switching between channels, and at least one of the enhancement layers may be adapted for providing fast switching by providing it with more random access points, e.g. more IDR-frames, than the base layer. | 11-07-2013 |
20130321576 | METHODS AND APPARATUS FOR ENCODING AND DECODING A MULTIVIEW VIDEO STREAM - A method for encoding a multiview video stream representing a plurality of viewpoints of a 3D scenery comprising objects, the method comprising for each of said viewpoints rendering and encoding a plurality of 2D video streams, respective ones of said plurality of 2D video streams including color information, depth information, and transparency information pertaining to objects in respective object layers serializing said plurality of 2D video streams into a combined 2D video stream; including said combined 2D video stream into said multiview video stream. | 12-05-2013 |
20150117518 | METHOD AND APPARATUS FOR ENCODING A VIDEO STREAM HAVING A TRANSPARENCY INFORMATION CHANNEL - Method for encoding a video stream having a transparency information channel in view of a predetermined target bit rate for said transparency information channel, comprising: tentatively applying a first encoding ( | 04-30-2015 |
20150117524 | METHOD AND APPARATUS FOR ENCODING A SELECTED SPATIAL PORTION OF A VIDEO STREAM - A method for encoding a selected spatial portion of an original video stream as a stand-alone video stream, said method comprising obtaining picture element information pertaining to said selected spatial portion; obtaining encoding hints derived from a complementary spatial portion of said original video stream that is peripheral to said selected spatial portion; and encoding said selected spatial portion with use of said encoding hints. | 04-30-2015 |
20150120954 | METHOD AND APPARATUS FOR ENCODING A VIDEO STREAM - A method for encoding a video stream divided in macroblocks using an encoding scheme, the video stream comprising a transparency level channel, said method comprising: —classifying said macroblocks into inner macroblocks, for which a transparency value provided by said transparency information channel is substantially uniform, and transition macroblocks, for which a transparency value provided by said transparency level channel is not substantially uniform; —determining a statistic of said transparency value for each one of said inner macroblocks; and —configuring a respective parameter of said encoding scheme for each one of said inner macroblocks in function of its respective statistic. | 04-30-2015 |
