RATE-DISTORTION OPTIMIZED QUANTIZATION METHOD |
| 摘要 |
A rate-distortion optimized quantization method includes determining a rate model and a distortion model respectively, establishing a rate-distortion objective function according to the rate model and the distortion model, estimating a closed-form solution for the rate-distortion objective function, and according to an input frame generating quantized transform coefficients using the closed-form solution. |
