    Abstract: A method for parallel processing of a video frame in accordance with principles of inventive concepts may include dividing the video frame into N tiles in a direction perpendicular to a raster scan direction; and sequentially encoding or decoding coding tree blocks included in each of the N tiles from a first row to an mth row according to the raster scan direction, wherein encoding or decoding of an Kth tile (K being a natural number more than 2 and less than N) starts at a point of time when encoding or decoding of coding tree blocks included in a first row of a (K−1)th tile is completed.

    Abstract: A multi core graphic processing device includes a first graphic core that processes a first segment of a graphic frame divided into a plurality of segments and generates a first local decision that defines a scene property of the first segment, a second graphic core that processes a second segment of the graphic frame different from the first segment and generates a second local decision that defines a scene property of the second segment, and a global decision unit that receives the first local decision and the second local decision from the first graphic core and the second graphic core, and selects one of the received first local decision and second local decision as a global decision.

    Abstract: A video/image compression method based on an region of interest (ROI) can be performed in a variable block video encoder such as a HEVC. A ROI coding method using variable block size coding information partitions a maximum coding unit (LCU) block obtained from an image into coding unit (CU) blocks. To obtain a quantization parameter of each coding unit (CU) block, the value of its quantization parameter is assigned based on its first hierarchical depth information and its second hierarchical depth information by using the first hierarchical depth information related to the size of the coding unit (CU) block and using the second hierarchical depth information related to the size of a prediction unit (PU) block correspondingly represented in consequence of the partition of the coding unit (CU) block. The resulting values of a quantization parameter assigned to different coding unit (CU) blocks may be different.

    Abstract: Provided are a depth information based optical distortion correction (ODC) circuit and method. The ODC circuit includes a depth acquisition unit acquiring a depth of an image, a grid generation unit dynamically generating a correction grid corresponding to the depth of the image using depth information of the image and a projection matrix, and a distortion correction unit correcting optical distortion in the image using the correction grid. The corrected image can then be stored, transmitted, or otherwise output. The image can be a single static image or photograph or a frame in a video recording.
