METHODS AND APPARATUS FOR IMPROVED QUANTIZATION ROUNDING OFFSET ADJUSTMENT FOR VIDEO ENCODING |
摘要 |
There are provided methods and apparatus for improved quantization rounding offset adjustment for video encoding and decoding. An apparatus includes a video encoder for encoding an input coding unit by determining a residual for the input coding unit corresponding to a difference between the input coding unit and a reference coding unit, applying a transform to the residual to obtain at least one transform coefficient, and quantizing the at least one transform coefficient by selecting a particular quantization step size and a rounding offset. |
