Abstract: A method and apparatus for searching, browsing and summarizing moving image data using the fidelity of a tree-structured moving image hierarchy, which can partition or divide the moving image data into predetermined units, extract a key frame or representative frame from each of the partitioned or divided units, create a tree-structured key frame hierarchy on the basis of the extracted key frames, store a fidelity value of each of the key frames, which is a sub-tree information representative degree of each key frame, at an edge between adjacent ones of the key frames, and effectively and efficiently search, browse and summarize the moving image data using the stored fidelity values. Therefore, a query image or video clip desired by a user can more rapidly and accurately be searched for.

Abstract: A method and apparatus for retrieving multimedia data using shape information. The multimedia data retrieval apparatus comprises a shape information feature extractor for receiving shape information of a query image and extracting a feature of the received shape information using a shape information descriptor based on eigen vectors of a multilayer covariance matrix, an image feature extractor for extracting a feature of each image data in the same manner as the shape information feature extractor, a multimedia database creator for creating a multimedia database on the basis of the features extracted by the image feature extractor, a similarity comparator for comparing the feature of the query image extracted by the shape information feature extractor with the features of the image data in the multimedia database to calculate similarities therebetween, and a compared result output unit for outputting the results calculated by the similarity comparator.

Abstract: A motion vector estimation apparatus in a digital video coding system and a method thereof. More particularly, the present invention relates to a motion estimation method and apparatus for, prior to a motion vector estimation operation, determining whether to perform it and selectively performing the motion vector estimation operation in accordance with the determined result, thereby reducing the coding time period and the amount of power consumed.

Abstract: A motion descriptor generating apparatus using accumulated motion histogram and a method therefor. Accumulated motion histograms are generated and motion descriptors are generated by using the accumulated motion histograms. The motion descriptor generating apparatus uses an accumulated motion histogram and includes a motion histogram generating unit for respectively generating a motion histogram with relation to intensity data and direction data of an input motion. An accumulated motion histogram generating unit generates a two-dimensional accumulated motion histogram in a predetermined sequence by using the motion histogram which is generated in the motion histogram generating unit. A motion descriptor generating unit structures (hierarchy structure) video into certain units according to a change amount of the accumulated motion histogram based on a lapse of time, which is generated in the accumulated motion intensity histogram generating unit.

Abstract: An apparatus for and a method of allocating D-channel to minimum channel when performing a basic rate interface (BRI) in WLL, in which D-channel is allocated to the minimum channel when connection is made to V5.

Abstract: All macro blocks (MB) decided as an “all_0”, “all_255” or “intra predicted” mode are transmitted as an “intra not coded” mode. A receiving terminal also separates “all_0”, “all_255” and “intra predicted” from the “intra not coded” mode, referring to pixels of a lower layer. “Inter coded && MVD=0” and “Inter coded && MVD!=0” modes are represented as “Inter coded”, and “Inter not coded && MVD=0” and “Inter not coded && MVD!=0” modes are represented as “Inter not coded”. As its result, coding modes on an I-picture can be reduced to two modes and coding modes on a P-picture, or a B-picture, can be lessened to four modes.

Abstract: A method and system for contour-based motion estimation for use with video images. The invention establishes corresponding contours (404, 414) in two images (402, 412) in a sequence of images, determines a motion vector which includes how the first contour (404) moved to become the second contour (414), and transmits the motion vector of the contour (414) in order to permit accurate display of the second video image (412). Preferably, boundary lines are removed from the contours before a comparison is made. The invention is computationally efficient and economical from a data transmission point of view, while enabling the production of accurate image.
