    • Provided is an image coding method for performing intra prediction achieving higher coding efficiency. The method for coding image data on a block-by-block basis includes: generating a predicted block by predicting a current block; computing a difference between the current block and the predicted block; coding the difference computed in the computing; decoding the difference coded in the coding; and adding the difference decoded in the decoding to the predicted block to generate a decoded block, wherein the generating includes: detecting an edge in a previously decoded block corresponding to a block adjacent to the current block; and extrapolating or interpolating previously decoded image data corresponding to a pixel included in the block adjacent to the current block, along a direction of the edge detected in the detecting to generate the predicted block.

    • The present invention relates to the field of video data de-interlacing, and in particular to a method for reconstructing full-resolution frames from a line-skipped-sequence of fields and a corresponding apparatus. It is the particular approach of the present invention to substitute missing lines of a block of a reconstructed full-resolution frame by lines from another field, e.g. the preceding field, and translating the substitute lines vertically and horizontally so as to optimized a smoothness measure computed for the thus reconstructed block. In this manner, an error-prone a priori determination of motion vectors based an interpolation of the interlaced images in the vertical direction can be avoided. The present invention may also be applied to sequences generated from a full-resolution sequence by a line-skipping operation that keeps only every Kth line and discards the other K−1 lines.
    • 本发明涉及视频数据去隔行的领域,特别涉及一种用于从行跳过序列的帧重构全分辨率帧的方法和相应的装置。 本发明的特定方法是通过来自另一领域的线例如重建的全分辨率帧的块的缺失线代替。 并且将替代线垂直和水平地平移,以便优化为这样重建的块计算的平滑度测量。 以这种方式,可以避免基于垂直方向上的隔行扫描图像的插值的容易出现的运动矢量的先验确定。 本发明还可以应用于通过跳过操作从全分辨率序列生成的序列,其仅保持每个第K行并丢弃另一个K-1行。
