摘要
FIELD: physics.;SUBSTANCE: disclosed is a method for fast selection of spatial prediction mode in a HEVC coding system. Analysis of the modulus of high-frequency horizontal and vertical components of the stationary wavelet of Haar transformation of an image of the encoded region is performed to construct a list of candidate modes. The process of constructing candidate modes consists of four steps. The first and second steps include making decisions to include a Planar mode and a DC mode in the list. The third step includes selecting angular candidate modes based on values in an array of vertical details and the fourth step includes selecting candidate modes based on analysis of the values of an array of horizontal details.;EFFECT: speeding up the encoding process by reducing the volume of computations when searching for an optimum block coding mode.
