Embodiment Construction
[0026] The present invention will be further described below in combination with specific embodiments.
[0027] A method for quickly skipping P and B frame intra-frame prediction modes in HEVC, specifically comprising the following steps:
[0028] (1) For the coding units of P and B frames, first calculate the coding costs of all inter-frame prediction modes according to the normal coding process, and select the inter-frame prediction mode with the smallest cost as the optimal inter-frame prediction mode, which is P_best_inter; After the encoding cost process, the predicted value and the number of coded bits of the prediction unit are saved. The predicted image of the luminance component of the optimal prediction unit is Prd_best_inter, and the number of coded bits is bits_best_inter;
[0029](2) Perform 1 / 4 downsampling on both the predicted image and the original image of the optimal inter-frame prediction mode P_best_inter, and then calculate SatdCost to obtain SatdCost_int...
