摘要： A method and apparatus for estimating the contour of a user object in a moving picture during video communications so that a personal background image is not provided during video communications. Information about center coordinates as well as a size of a face of the user object is extracted from a moving picture frame. Edges are extracted from the moving picture frame, and a boundary of a head of the user object is estimated using a semicircle. The boundaries of left and right shoulders and left and right arms of the user object are estimated using second-order function graphs that overlap a largest portion of the edges. An entire contour of the user object is estimated according to the boundaries of the head, the left and right shoulders, and the left and right arms of the user object.

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 for encoding a multiview video includes estimating and compensating for a motion between a plurality of pictures from more than one view. A first video captured at a first view becomes a basis and for performing encoding on the first video using the motion estimation and compensation result. Motion estimation and compensation is then performed on a predetermined picture selected from among a plurality of pictures included in a second video captured at a second view being different from that of the first video. The picture from the second view is then encoded using the motion estimation and compensation result. A bit stream is generated including encoded data of the first video and encoded data of the second video.

摘要： A method and apparatus for error concealment in decoding of a moving picture. The method includes the steps of determining an erroneous macro block in a present frame when the moving picture is decoded, finding a first macro block having a highest similarity to the erroneous macro block and a second macro block having a next highest similarity to the erroneous block in a previous frame by comparing adjacent pixels of respective blocks in the previous frame with adjacent pixels of the erroneous block in the present frame; and replacing the erroneous block by using an average between the found macro blocks having the highest similarity and the second highest similarity to thereby conceal the erroneous macro block. The apparatus includes a parser, an entropy decoder, an inverse quantizer, an inverse converter, and a concealment unit that uses motion compensation from a previous frame to correct a macro block in a current frame.

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.
