Abstract
A prediction direction selection method includes constructing, according to texture consistency of a prediction unit relative to an upper-layer coding unit of the coding unit in which the prediction unit is located, a reference direction corresponding to the prediction unit. The method also includes obtaining, for the coding unit, preliminarily selected direction vectors that are selected from intra-frame directions according to rate-distortion costs. The method next includes determining processed candidate direction vectors by using the reference direction and the preliminarily selected direction vectors. The processed candidate direction vectors are used for selecting a direction corresponding to an optimal cost as a prediction direction for unit prediction performed for the coding unit.
