• Rate-Distortion Optimization in High Efficiency Video Coding promotes the coding efficiency, but also imposes intensive computation to the encoder, because the complex Syntax-based context-adaptive Binary Arithmetic Coding is performed for each candidate coding configuration. We develop the classification based regression method to derive the rate models, which fast estimate the bit cost of quantization coefficient block from its distribution features. Experiments demonstrate that, our method reduces the averaged 28.4% computation time in rate cost estimation, while the coding efficiency degradation is 0.0428dB.
