30 Jun 2004TL;DR: This work proposes an algorithm that takes into account the correlation/continuity of motion vectors among different reference frames and shows that the algorithm effectively reduces the computations of MRF-ME, and achieves similar coding gain compared to the full-search approach.
Abstract: Multiple reference frame motion compensation is a new feature introduced in H.264/MPEG-4 AVC to improve video coding performance. However, the computational cost of multiple reference frame motion estimation (MRF-ME) is very high. We propose an algorithm that takes into account the correlation/continuity of motion vectors among different reference frames. We also show that the algorithm effectively reduces the computations of MRF-ME, and achieves similar coding gain compared to the full-search approach.

17 Oct 2006TL;DR: In this paper, the authors propose a method for processing multimedia data to generate progressive frame data from interlaced frame data. But the method is limited to the use of a spatial filter module to generate spatio-temporal information and motion estimator to generate motion information.
Abstract: The invention comprises devices and methods for processing multimedia data to generate progressive frame data from interlaced frame data. In one aspect, a method of processing multimedia data includes generating spatio-temporal information for a selected frame of interlaced multimedia data, generating motion information for the selected frame, and deinterlacing fields of the selected frame based on the spatio-temporal information and the motion information to form a progressive frame associated with the selected frame. In another aspect an apparatus for processing multimedia data can include a spatial filter module configured to generate spatio-temporal information of a selected frame of interlaced multimedia data, a motion estimator configured to generate motion information for the selected frame, and a deinterlacer configured to deinterlace fields of the selected frame and form a progressive frame corresponding to the selected frame based on the spatio-temporal information and the motion information.

07 Dec 2003TL;DR: In this article, a physical layer frame is formed by dynamically varying an aggregate packet size in response to a condition of a channel used for communicating voice and/or data, where each content frame may include a voice frame or a data frame.
Abstract: A method of the communication includes communicating at least one physical layer frame. The physical layer frame is formed by dynamically varying an aggregate packet size in response to a condition of a channel used for communicating voice and/or data. Here, the step of dynamically varying aggregate packet size may involve modifying a number of content frames to form the physical layer frame. The physical layer frame may correspond with a payload having at least two content frames and at least one IP header. Each content frame may include a voice frame and/or a data frame.

TL;DR: In this article, a method and system for compressing and decompressing a sequence of image frames is disclosed, which includes an intraframe decomposition process (24, 24') performed upon each frame in both the row and column directions, including an mth order averaging and differencing operation.
Abstract: A method and system for compressing and decompressing a sequence of image frames is disclosed. According to the disclosed embodiments of the invention, the compression process includes an intraframe decomposition process (24, 24') performed upon each frame in both the row and column directions, including an mth order averaging and differencing operation (56, 62). Each frame is then combined with others in an adjacent pair or group of four by way of an interframe decomposition (28). Quantization (30) is then performed, preferably by division of each coefficient by a quantizer (ρ) associated with the one of the frequency component subbands containing the coefficient. Reconstruction of the compressed frames is accomplished by performing the inverse of the compression process. According to the disclosed embodiments, either the compression or decompression processes and systems performs Cholesky filtering (60, 66; 170, 172), preferably in a recursive manner by way of forward and backward filtering. In this way, one or the other of the compression system (CS) or decompression system (DS) is relieved from a significant amount of computing burden.

TL;DR: In this article, representative points vicinal to a detected contour line of an image-segmented input picture are corrected in position so that lattice links connecting the representative points extend along the detected contours line, and motion vectors are detected at the corrected representative points, before a motion vector at each pixel in the picture is interpolated from the detected motion vectors at representative points near thereto, for a motion-compensated inter-frame prediction small of a deformed distortion.
