METHOD, APPARATUS AND DEVICE FOR OBTAINING VIDEO IMAGE MOTION INFORMATION AND TEMPLATE CONSTRUCTION METHOD |
摘要 |
A method, an apparatus and a device for obtaining motion information of video images are provided. The method includes: determining at least one first candidate reference block corresponding to a current block in a first reference frame according to known motion information related to the current block; determining at least one second candidate reference block that is respectively corresponding to the at least one first candidate reference block in a second reference frame; calculating a sum of differences between a first candidate reference block and a second candidate reference block corresponding to the first candidate reference block; and selecting the first candidate reference block and the second candidate reference block which have the minimal sum of differences as a first reference block and a second reference block of the current block, and obtaining motion information of the current block according to motion information determined by the first reference block and the second reference block. A template construction method is also provided. The method, apparatus and device can improve the encoding and decoding efficiency of video images. |
