摘要： A method for estimating a boundary between a background and a user object in a video, in which the user object is segmented from the background is provided. The initial object contour is estimated in a first video frame for object segmentation, and color probability density functions are estimated for the user object and the background segmented from the first video frame. An edge strip with a predetermined width is generated in a current frame based on an object contour of a previous frame, and a coherence probability density function of the edge strip is estimated. The user object is segmented in the current frame by energy minimization.

摘要： A method and apparatus for generating a thumbnail image are provided so that the out-of-focus (OOF) information can be ascertained from looking at the thumbnail. An input image is decoded, and a degree of the amount of OOF of the decoded image is measured (OOF information). There is a determination as to whether or not there is an EXchangeable Image File (EXIF) information about the input image. In the presence of EXIF information, a thumbnail image is extracted from the EXIF information and as much an OOF effect is applied to the thumbnail image in accordance with the degree of OOF. In the absence of the EXIF information, a thumbnail image is generated by scaling down the decoded image at a down scaler and applying as much of an OOF effect is applied to the thumbnail image in accordance with the degree of OOF.

摘要： A motion search method and apparatus for minimizing an off-chip memory access to reduce cycles for predicting a motion vector. A sum of absolute differences (SAD) calculation processing is performed, while an off-chip memory is accessed using Direct Memory Access (DMA). A position of a current macro block is determined if a frame is input and the length of a horizontal search line is set according to adjacent motion vectors and predetermined external parameters. The SADs are calculated by calculating medians of the adjacent motion vectors as a predictive motion vector, setting a vertical direction value of the predictive motion vector as an initial search line, and sequentially searching at least one horizontal search line, and determining a position of a minimum SAD from the at least one horizontal search line. The minimum SAD position is selected as a final motion vector.
