摘要： The restoration of images by vector quantization utilizing visual patterns is disclosed. One disclosed embodiment comprises restoring detail in a transition region of an unrestored image, by first identifying the transition region and forming blurred visual pattern blocks. These blurred visual pattern blocks are compared to a pre-trained codebook, and a corresponding high-quality visual pattern blocks is obtained. The high-quality visual pattern block is then blended with the unrestored image to form a restored image.

摘要： Disclosed herein are exemplary embodiments of methods, apparatus, and systems for performing content-adaptive deblocking to improve the visual quality of video images compressed using block-based motion-predictive video coding. For instance, in certain embodiments of the disclosed technology, edge information is obtained using global orientation energy edge detection (“OEED”) techniques on an initially deblocked image. OEED detection can provide a robust partition of local directional features (“LDFs”). For a local directional feature detected in the partition, a directional deblocking filter having an orientation corresponding to the orientation of the LDF can be used. The selected filter can have a filter orientation and activation thresholds that better preserve image details while reducing blocking artifacts. In certain embodiments, for a consecutive non-LDF region, extra smoothing can be imposed to suppress the visually severe blocking artifacts.

摘要： Exemplary generic file storage for scalable media is described. In one implementation, stored scalable media streams are related as nodes of a directed acyclic graph (DAG) in which directed edges between the nodes describe relationships between scalable media streams. Many different presentations of a media content can be delivered from a DAG storage file. Data space is reduced because different presentations can avail of the same sub-trees in the DAG. In one implementation, exemplary DAG storage files for scalable media have an information structure that allows the DAG file to self-tailor and/or allocate the scalabilities of the media content presentations it is capable of delivering in order to suit the characteristics of a requesting entity.

摘要： Improved video coding is described to encode video data within a sequence of video frames. To this end, at least a portion of a reference frame is encoded to include motion information associated with the portion of the reference frame. At least a portion of a predictable frame that includes video data predictively correlated to said portion of said reference frame is defined based on the motion information. At least said portion of the predictable frame is encoded without including corresponding motion information and including mode identifying data. The mode identifying data indicate that the encoded portion of the predictable frame can be directly derived using at least the motion information associated with the portion of the reference frame.

摘要： Wyner-Ziv and wavelet video coding is described. In one aspect, Wyner-Ziv frames from multiple frames of source video content are zero-tree entropy encoded to generate encoded Wyner-Ziv content. The zero-tree entropy encoding operations are based on high-order statistical correlations among wavelet transforms from the Wyner-Ziv frames. The encoded Wyner-Ziv content is communicated to a decoder for decoding to generate reconstructed Wyner-Ziv frames for presentation to a user.

摘要： A method for compressing a high dynamic range (HDR) texture. A first block of texels of the HDR texture in a red-green-blue (RGB) space may be transformed to a second block of texels in a luminance-chrominance space. The first block may have red values, green values and blue values. The second block may have luminance values and chrominance values. The chrominance values may be based on a sum of the red values, a sum of the green values and a sum of the blue values. The luminance values and the chrominance values may be converted to an 8-bit integer format. The luminance values may be modified to restore a local linearity property to the second block. The second block may be compressed.
