Abstract: A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.

Abstract: A method of detecting the alignment error of lenses and reducing image distortion attributable to the alignment error in a lens-type 3-dimensional liquid crystal display monitor. A method of detecting the alignment error of lenses in a 3D display using a purpose-built test pattern image, which predicts the alignment error in such a way as to calculate variation in view indices of pixels in a lateral direction, observed by an eye of an observer, if there is alignment error in the lenses. A method of compensating for image distortion in a 3D monitor, including the steps of finding the relationship between the pixels of a Liquid Crystal Display (LDC) panel and the pixels of observed images, which are determined depending on the location of an observer; and compensating for image distortion attributable to the rotational and translational alignment error of the lenses based on the found relationship.

Abstract: A method for motion vector coding of an MPEG-4 includes determining motion vector candidates, and selecting a candidate having a minimum bit rate among motion vector candidates in an encoder. A motion vector prediction error and prediction mode information and then to a decoder. The decoder estimates a minimum bit rate for coding a motion vector difference and codes a motion vector against components X and Y, using a minimum rate predictor.

Abstract: A method for estimation of a motion image and an apparatus therefor are provided.

Abstract: A method for coding a motion vector in a moving picture reduces overall bit rates in a process of moving picture coding includes searching a motion vector prediction candidate for a first block among a plurality of blocks in a macroblock, searching a plurality of motion vector prediction candidates for each of additional blocks in the plurality of blocks in succession upon completion of the search for the plurality of motion vector prediction candidates for the first block. A motion vector median prediction value for the first block is compared to a motion vector bound. If the motion vector median prediction value is determined to lie within a motion vector bound, a predicted value for coding the first block is determined to be the motion vector median prediction value.

Abstract: A method for estimating a motion vector in a moving picture is disclosed, that selectively uses a bilinear interpolation to estimate a motion vector, which reduces a computational complexity. The method includes estimating Y component motions of all macroblocks and determining a coding prediction mode when a motion vector is obtained. Then, blocks for which the coding prediction mode is determined to be INTER mode are searched for halfpels. A vector having a smaller SAD to an 8×8 block in question from motion vectors (MVibil) obtained by a bilinear interpolation of a 16×16 block motion vector(MV6) and motion vectors of blocks around the 16×16 block is selected as an initial motion vector. A local search of the initial motion vectors of the 8×8 blocks in a ±2 search region is made when the initial vectors of the 8×8 block are determined. Then, a ±0.5 halfpel search is again made to obtain final motion vectors.

Abstract: A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S.sub.0, S.sub.1, and S.sub.2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.
