    摘要: New intra angular prediction modes and methods for decoding are offered for providing greater accuracy when processing predictions of digital video data blocks. One new method considers predicting a current prediction sample by taking the linear interpolation of two previously reconstructed reference samples that lay along a common angular line. Another new method offers a method for making previously unavailable samples from a neighboring block available as reference samples when predicting a current prediction sample. Another new method considers a new combined intra prediction mode that utilizes a local mean to predict a current prediction sample. And a new decoding method offers to rearrange the order in which video data blocks are predicted based on the intra prediction mode used for predicting the video data blocks.

    摘要: 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.
