APPARATUSES AND METHODS FOR PROVIDING OPTIMIZED QUANTIZATION WEIGHT MATRICES |
| 摘要 |
Apparatuses and methods for providing optimized quantization matrices are disclosed herein. An example apparatus may include an encoder. The encoder may be configured to provide a plurality of coefficients based, at least in part, on a frame and to provide an optimized quantization weight matrix based, at least in part, on the plurality of coefficients during a first encoding pass. The encoder may further be configured to quantize the plurality of coefficients in accordance with the optimized quantization weight matrix during a second encoding pass different than the first encoding pass. |
