摘要： A texture-based image database browsing and sorting method computes the number of edge pixels of objects in static images, measures textures of the static images by numerating the number of edge pixels thereof and measures a texture of a query image by numerating the number of edge pixels of an object in the query image. Then, the method sorts the measured textures according to a sorting order and searches a texture close to the texture of the query image among the sorted textures.

摘要： A camera information coding/decoding method for synthesizing stereoscopic real video and a computer graphic image is disclosed. The method stores the camera information generated when picturing, which is not contained in the existing multimedia contents coding standard, that is, the location motion information of the camera and the camera viewpoint displacement information, together with contents as the camera motion information stream. The camera information obtained through the camera position sensor and the camera viewpoint displacement sensor when picturing image is coded and stored together with the contents, thereby easily and precisely synthesizing with the computer graphic image. In addition, since the information may be easily transformed to the descriptor of the camera motion information of MPEG-7 format, there is another advantage of easily carrying out camera motion information indexing operation among searching methods of the multimedia contents.

摘要： Provided is a method for performing hierarchical B picture-based coding on a video sequence using the structure of adaptively divided group of pictures (GOP). The method includes the steps of, for each predefined 2N frame-sized group of pictures (GOP) of the video sequence, (a) encoding the 2N frame-sized GOP of the video sequence based on each of the different GOP sizes from the maximum size, 2N, to the minimum size, 2M (M is an integer between 1 and N) and obtaining different values between frames reconstructed after the encoding is performed and frames after the hierarchical B-picture prediction is performed, based on each of the different GOP sizes; (b) selecting at least one sub-GOP based on the difference values obtained by encoding the 2N frame-sized GOP of the video sequence based on each of the different GOP sizes; and (c) generating a bitstream by encoding the 2N-frame-sized GOP based on the at least one selected sub-GOP. Thereby, the hierarchical B picture-based video coding is performed by adaptively dividing the GOP size based on performance and thereby obtains high coding efficiency.
