摘要： A hybrid imaging device is configured to capture low resolution video and high resolution still images. The imaging device is configured to apply motion information obtained from the low resolution video to a reference high resolution still image to generate a missing moment of interest high resolution still image. The low-resolution video is captured at a high frame rate in conjunction with a few high-resolution still pictures taken at periodic intervals. A user locates a desired scene of interest, e.g. a moment of interest, from the captured video, and a post-processing technique is used to generate the high resolution still picture corresponding to the selected moment of interest. The high resolution still image is generated using texture information from one or more nearby captured high resolution still images and motion information from the low-resolution video frame corresponding to the selected moment of interest.

摘要： A codec configured to operate in a sequential mode extends the current AVC standard in order to provide support for coding high resolution still image pictures within the AVC coding of a lower resolution video. The sequential mode codec is configured according to the modified AVC standard. The codec is capable of capturing an AVC video stream while concurrently capturing high resolution still images at random intervals relative to the video stream. Each captured high resolution still image is embedded within the video stream. The video stream including the embedded high resolution still images is encoded as a single layer bit stream. Each embedded high resolution still image signals or forces the start of a new GOP in the coded video sequence. The AVC standard is extended to include new syntax for the sequence parameter sets. In one embodiment, a modified sequence parameter set defines a new profile that signals the presence of a high resolution still image in sequence with AVC video.

摘要： Method and apparatus for intra-prediction in a video encoder are described. An aspect relates to a method of intra-prediction for a group of samples in an image being coded. In some examples, the method includes: defining a target template for the group of samples; comparing the target template with affine transformations of candidate templates within a search area of the image; identifying at least one matching template of the candidate templates as matching the target template; determining a candidate group of samples based on the at least one matching template; and coding the group of samples using the candidate group of samples as a predictor.

摘要： The currently existing ISO/AVC file format is modified by providing extensions to store and access video content currently being defined by the SVC standard. Specifically, extensions to the AVC file format are made to provide a new SVC file format that enables the storage and access of scalable video data. The scalable video data is stored as a single track within a media data section of the SVC file format. New extensions are defined for description entries and boxes within a metadata section of the SVC file format. These extensions provide means for extracting sub-streams or layers from the single track of scalable video data stored in the media data section.

摘要： An apparatus or method of efficiently coding high resolution video using texture analysis and synthesis techniques in a scalable video coding framework. A high-resolution video signal is spatially downsampled and encoded into a base-layer. Texture and structure information are extracted from the downsampled signal and base-layer for use by a texture synthesizer. The texture synthesizer is structurally and texturally aware utilizing edge information from a base-layer of the synthesizer to improve synthesis. After synthesis, a video quality assessor directs enhancement-layer coding of unacceptably synthesized areas by alternate (non-textural) coding means, such as conventional AVC or MPEG-2 coding. In one mode, the quality assessor iteratively improves synthesis of certain blocks to make them acceptable for enhancement-layer coding. The apparatus or method outputs a bit stream, or bit streams, containing both the coded base-layer and the enhancement-layer.
