    • Methods and apparatuses for encoding and decoding video are provided. The encoding method includes: performing motion estimation on a current block according to a first sub-pixel unit, and obtaining a motion vector in the first sub-pixel unit with respect to the current block; interpolating a reference picture indicated by the motion vector according to a second sub-pixel unit smaller than the first sub-pixel unit; using the interpolated reference picture, selecting a second sub-pixel in the second sub-pixel unit adjacent to a first sub-pixel in the first sub-pixel unit of the reference picture; selecting a corresponding region that has a smaller error with the current block, from among a first corresponding region of the reference picture and obtained with respect to the first sub-pixel, and a second corresponding region of the current block and obtained with respect to the selected second sub-pixel; and encoding information of the selected corresponding region.
    • 提供用于编码和解码视频的方法和装置。 编码方法包括:根据第一子像素单元对当前块执行运动估计,并获得关于当前块的第一子像素单元中的运动矢量; 根据比第一子像素单元小的第二子像素单元内插由运动矢量指示的参考图像; 使用内插参考图像,在与参考图片的第一子像素单元中的第一子像素相邻的第二子像素单元中选择第二子像素; 从参考图像的第一对应区域中,相对于第一子像素选择与当前块具有较小误差的对应区域,以及当前块的第二对应区域,并相对于 选择的第二子像素; 以及编码所选择的对应区域的信息。
