Abstract
A method and an apparatus for video coding for reducing block boundary discontinuity includes using additional neighboring pixels of the current block or additional pixels of a referenceable picture toward prediction techniques with no use of neighboring pixels. The video coding method and the apparatus improve the predictor of the current block.
Claims19
A method performed by a video decoding device for predicting a current block, the method comprising:
- decoding, from a bitstream, motion information that is of the current block and includes a reference picture index of the current block and a motion vector of the current block;
- generating a first predictor of the current block by performing an inter prediction based on the motion information of the current block;
- generating a second predictor of the current block by using information on adjacent blocks of the current block and the motion information of the current block;
- deriving weights for the first predictor and the second predictor by using the information of the adjacent blocks of the current block and the motion information of the current block;
- and
- generating a final predictor of the current block by weighted summing the first predictor and the second predictor by using the weights.
