TL;DR: In this article, a method and apparatus for encoding and decoding a motion vector of a current block is presented. But the method of encoding is based on estimating the motion vector and determining a first motion vector predictor candidate from among a plurality of candidate motion vectors.

TL;DR: In this paper, a method and apparatus for reducing block artifacts during a residual prediction in a multilayer-based video coding are disclosed, which includes obtaining a difference between a predicted block for a second block of a lower layer, which corresponds to a first block included in a current layer, and the second block; adding the obtained difference to a predicted blocks for the first block; smoothing a third block generated as a result of the addition using a smoothing function.

TL;DR: In this paper, a method and apparatus of encoding a video, including encoding the video data of maximum coding unit based on deeper coding units of hierarchical structures according to at least one split region of the maximum coding units, with performing inter prediction using partitions obtained by splitting the coding unit according to arbitrary ratios, and determining a coding depth.

TL;DR: In this article, a video coding and decoding method using a weighted prediction and an apparatus for the same are provided, where the video coding method includes generating a predicted image for a present block, generating a weighting factor which is a scaling factor of the predicted image that minimizes the difference between the present block and predicted image, and coding a residual signal generated by subtracting the weighted prediction image from the current block.

TL;DR: In this paper, a video encoding method and a video decoding method and apparatus are provided in which a processing order for predetermined-size blocks included in a macroblock is defined in order to efficiently use spatial correlation in an image.
