    摘要: A method is provided for constructing a video frame in a video signal processing apparatus using multi-core processing, in which multiple macro blocks are generated from a video signal on a predetermined unit basis, and a video frame is constructed by combining the generated multiple macro blocks with header information. The video frame includes one correlation information field for recording information about correlations between the multiple macro blocks, and the one correlation information field is located in front of the multiple macro blocks constituting the video frame.

    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.
