摘要： Coding a video stream having a plurality of frames is disclosed. A frame of a video stream is processed to determine if direct motion prediction can be applied to the macroblocks of the frame. Macroblocks to which direct motion can be applied are grouped into superblocks. The distribution of superblock size and configuration is analyzed to determine variable-length codes that can vary for each frame or segment encoded using direct prediction superblocks, thereby reducing the number of bits used to indicate superblock encoding in the encoded video stream.

摘要： Techniques for efficient coding of digital media data are presented. A resource controller component dynamically allocates computing resources between an estimator component and a coder component. The estimator component generates initial motion estimation of a raw video frame of a sequence, based on a previous raw video frame, in parallel with the coder component encoding the previous raw video frame to generate a reconstructed previous video frame. The coder component encodes the raw video frame based on the reconstructed previous video frame. The coder component can dynamically allocate initial subsets of bits for respective coding units of the raw video frame based on residual data identified from the initial motion estimation. After completing encoding of a specified number of coding units, the coder component can dynamically adjust bit assignments for remaining coding units of the raw video frame based on initial residual data and identified real residual data.

摘要： Methods for generating depth maps from monocular still image or monocular video and systems using the same are provided. First, an initial depth map is estimated or arbitrary defined. For video inputs, motion information can be used, for still image the initial background can be arbitrary set by default, chosen by the user or can be estimated. Estimation of the initial depth map can be based on a contrast map or a blur map. The initial depth map defines initial depth values for the respective pixels of the monocular image or monocular motion picture frames. The respective pixels of the original image or video frame data are mapped to the initial depth map according to positions of the pixels, in order to obtain corresponding initial depth values. An image data space of the image is subdivided into a plurality of sub-image spaces, and the initial depth value of each of the pixels of the image is filtered according to the initial depth values of the pixels located in the same sub-image space, in order to obtain depth information for the pixels.

摘要： A method determines core geographical information in a document by computing a score for each geographical name found in the document. The computation of the score uses the appearance frequency of the respective geographical name and positional weights assigned to various types of appearance positions of the geographical name in the document. The system determines the core geographical information in the document based on the scores of the geographical names found in the document. The method may further compute aggregated scores of geographical regions related to the geographical names and determine the core geographical information using both the aggregated scores of geographical regions and the scores of individual geographical names to increase accuracy.
