Quick prediction mode selection method based on frame from video standard regression model

The present invention discloses a video standard based on an intra prediction mode from the rapid regression model selection methods, mainly to solve the conventional H.265 / HEVC standard high complexity intra prediction mode selection problem. Which is implemented steps of: for the coarse mode current prediction unit selected candidate model to obtain m; most probable mode was added, to obtain m1 candidate modes; cost function value m1 candidate modes in ascending order; two adjacent both the difference and the cost values ​​based on the average ratio obtained from the regression model to compare the threshold adaptively selected n types of final candidate for rate distortion optimization mode. Simple operation of the present invention, while maintaining the image compression performance, shorten the operation time, provide a technical basis for real-time implementation H.265 / HEVC standard, for all based on H.265 / HEVC video compression coding standard of the end intra prediction mode selection.
