Abstract
This disclosure relates to the field of video coding and decoding technology, and particularly, to a method and an apparatus for coding and decoding videos, wherein the coding method comprises: acquiring available neighboring pixel points which are reconstructed and neighboring to a coding unit; finding a reference block corresponding to the coding unit according to the motion vector of a prediction unit for a pixel attribute in the coding unit, and acquiring corresponding reference pixel points around the reference block; calculating a pixel attribute compensation parameter of the prediction unit using a value of the pixel attribute of the neighboring pixel point and a value of the same pixel attribute of the reference pixel point; and calculating a first prediction value of the prediction unit according to the pixel attribute compensation parameter, and coding the coding unit according to the first prediction value.
