  • Publication number: 20150015683
    Abstract: A method and apparatus for processing a multi-view image are provided. A priority may be assigned to each hole pixel in a hole region generated when an output view is generated. The priority of each hole pixel may be generated by combining a structure priority, a confidence priority, and a disparity priority. Hole rendering may be applied to a target patch including a hole pixel having a highest priority. The hole pixel may be restored by searching for a source patch most similar to a background of the target patch, and copying a pixel in the found source patch into a hole pixel of the target patch.

  • Publication number: 20130044044
    Abstract: A display device and a fabrication method thereof are provided. In a dual-link structure for a narrow bezel, first link wirings are formed on the same layer that the gate lines are formed and second link wirings are formed on the same layer that the data lines are formed. The first link wirings and the second link wirings are formed in a non-display area. Or auxiliary link wirings are further formed over the first link wirings and the second link wirings respectively. Or the first link wiring and second link wiring are divided two pieces of sub-link wirings. The sub-link wirings consisting the one link wiring are connected respectively and are formed on the different layer, whereby a defective image due to a difference in resistance between neighboring link wirings can be improved.
