Publication number: 20160381395Abstract: 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.Type: ApplicationFiled: September 12, 2016Publication date: December 29, 2016Inventors: Hyun Mun Kim, Jong Beom Ra, Sung Deuk Kim, Young Su Lee

Patent number: 8073056Abstract: A motion vector searching system and method estimates a motion vector during image compression by acquiring a present image frame and at least one previous image frame, generating low-resolution images of the present and previous frames in multiple stages, determining areas in one of the stages in which pixel searches are to be performed, locating at least two areas which overlap, and then merging the overlapping areas if a merge condition is satisfied. The search areas are determined by identifying candidate points in the low-resolution image which have low pixel absolute difference values, and the merge condition may correspond to a certain minimum distance between centers of the overlapping areas. A motion vector estimator is used to perform additional searching in the merged and non-merged areas to generate a motion vector associated with the present and previous image frames.Type: GrantFiled: July 13, 2006Date of Patent: December 6, 2011Assignee: LG Electronics Inc.Inventor: Sung Deuk Kim

Patent number: RE42516Abstract: A method of coding a moving picture reduces blocking artifacts. The method includes defining pixel sets S0, S1, S2 around a block boundary, selectively determining a deblocking mode as a default mode or a DC offset mode depending on the degree of blocking artifacts. If the default mode is selected, frequency information is obtained around the block boundary per pixel using a 4-point DCT kernel, for example, a magnitude of a discontinuous component belonging to the block boundary is replaced with a minimum magnitude of discontinuous components belonging to the surroundings of the block boundary in the frequency domain and the replacing step is applied to the spatial domain. If the DC offset mode is selected and a determination is made to perform DC offset mode, the blocking artifacts in a smooth region are removed in the DC offset mode.Type: GrantFiled: September 7, 2007Date of Patent: July 5, 2011Assignee: Video Enhancement Solutions, LLCInventors: Hyun Mun Kim, Jong Beom Ra, Sung Deuk Kim, Young Su Lee
