Method of and apparatus for video encoding and decoding based on motion estimation
TL;DR: In this paper, a method for video encoding and decoding based on motion estimation is proposed. But the method is not suitable for video streaming and cannot be used in the case of high-quality video data.
Proceedings ArticleDOI
Study of decoder complexity for HEVC and AVC standards based on tool-by-tool comparison
TL;DR: Several selected coding tools including intra prediction, motion compensation, transform, loop filters and entropy coder have been analyzed in terms of number of operations as well as their statistical differences for providing initial complexity estimates of the HEVC decoder compared with the H.264/AVC decoder.
Patent
Method for compressing/decompressing motion vectors of unsynchronized picture and apparatus using the same
TL;DR: In this paper, a method for improving the compression efficiency of motion vectors of an unsynchronized picture by efficiently predicting the motion vectors using motion vectors from a lower layer is presented.
Patent

Woo-Jin Han,Bae-Keun Lee +1 more
TL;DR: In this article, a method of reducing mismatch between an encoder and a decoder in a motion compensated temporal filtering process and a video coding method and apparatus using the same was proposed.
Patent
Method and apparatus for encoding and decoding image by using filtered prediction block
TL;DR: In this article, a prediction block of a current block is created by performing intra prediction or inter prediction on the current block and the prediction block is filtered by using a predetermined filter.
