Method and apparatus for encoding and decoding image by using multiple reference-based motion prediction |
摘要 |
Provided are a method and apparatus for encoding an image by using motion prediction and a method and apparatus for decoding an image by using motion prediction. The method of encoding an image by using motion prediction, the method includes: determining at least one candidate predictor set including at least one candidate predictor within a candidate predictor range away from a location of a current predictor in a reference frame; determining a reference predictor based on a distortion rate of hypothesis predictors determined according to the at least one candidate predictor of each of the at least one candidate predictor set; performing motion prediction with regard to a current frame by using a reference block corresponding to the reference predictor and a current block; and encoding image data including the current frame based on a result of the motion prediction.
