  • Publication number: 20150146103
    Abstract: A method for processing a video signal according to the present invention comprises the steps of: determining a motion vector list comprising at least one of a spatial motion vector, a temporal motion vector, and a mutation vector as a motion vector candidate of a target block; extracting motion vector identification information for specifying the motion vector candidate to be used as a predicted motion vector of the target block; setting the motion vector candidate corresponding to the motion vector identification information as the predicted motion vector of the target block; and performing motion compensation based on the predicted motion vector. The present invention forms the motion vector candidate and derives the motion vector of the target and derives the motion vector of the target block therefrom, thus enabling a more accurate prediction of the motion vector, and thereby reduces the amount of transmitted residual data and improves coding efficiency.

  • Publication number: 20150117517
    Abstract: The present invention variably adjusts the maximum splitting information of a conversion unit according to the type of prediction unit and the splitting information on a coding unit and selects the optimal splitting information on the conversion unit. The present invention determines the maximum splitting information on the conversion unit of a depth block by using the maximum splitting information on the conversion unit for texture data. The present invention may lower complexity without a loss in efficiency by variably adjusting the maximum splitting information on the conversion unit in consideration of the characteristics of the depth data. The present invention may lower complexity by determining the maximum splitting information on the conversion unit of the depth data by using similar characteristics between the texture data and the depth data.

  • Publication number: 20150098509
    Abstract: The method for processing video signals according to the present invention involves deriving an inter-view motion vector of the current texture block from one of inter-view motion vector candidates in consideration of a priority among the inter-view motion vector candidates of the current texture block, and performing inter-view inter-prediction for the current texture block using the derived inter-view motion vector. The present invention enables more accurate inter-view motion vector prediction from among various inter-view motion vector candidates, and thus a reduction in the amount of residual data being transmitted, thereby improving coding efficiency.

  • Publication number: 20150055702
    Abstract: According to the present invention, a method of processing a video signal includes the steps of: receiving the depth data corresponding to a given block containing present pixels; determining a variation of the depth data; comparing the variation of the depth data with a predetermined value; if the variation is less than the predetermined value, coding the present pixels by using a first partial filter, and if the variation is greater than the predetermined value, coding the present pixels by using a second partial filter; wherein the second partial filter is applied to a wider range than the first partial filter. Accordingly the image quality of improved; the complexity according to the filter application is reduced; and at the same time variable filtering may improve the coding efficiency.

  • Publication number: 20150043636
    Abstract: The present invention encodes a warp map by using a video codec such as a multi-view texture image by a warp converter, and decodes a warp map by using a video codec such as a multi-view texture image by using a warp inverter. The present invention may incur less additional costs because it does not use a dedicated warp map coder. In addition, the present invention may convert a warp map by using a warp map converter and send the converted map to an encoder and invert decoded warp map information by using a warp map inverter so that the warp map is encoded and decoded by using a video codec such as a multi-view texture image. In addition, it is possible to increase compatibility by enabling various kinds of supplementary data to be used. In addition, it is possible to increase technique compatibility by simply applying a warp map scheme to a 3D video coding technique using a depth map.

  • Publication number: 20140205011
    Abstract: The present invention relates to an intra prediction method for predicting pixel values within a prediction target block on the basis of a plurality of peripheral pixels adjacent to the prediction target block. The intra prediction method according to the present invention includes the steps of: receiving and decoding encoded image information; determining a target boundary by determining a plurality of boundary pixels representing the target boundary within the prediction target block on the basis of the decoded image information; determining a plurality of prediction target regions partitioned on the basis of the target boundary within the prediction target block; and performing a prediction for each of the plurality of prediction target regions on the basis of peripheral pixels differing from each other selected from among the plurality of the peripheral pixels.

  • Publication number: 20140146137
    Abstract: Disclosed are an encoding/decoding method and apparatus using a skip mode. The image decoding method comprises: generating a warping prediction depth image unit, and then decoding skip information regarding an image unit to be decoded; and decoding the image unit to be decoded using a skip mode based on the skip information. The skip information may be determined based on depth information of the warping prediction depth image unit, depth information of the image unit to be decoded, or edge information of a text picture image unit corresponding to the image unit to be decoded. Thus, an unnecessary prediction process need not be performed during the encoding and decoding of the image unit, thereby improving image encoding and decoding efficiency.
