ВЫСОКОТОЧНАЯ ПОВЫШАЮЩАЯ ДИСКРЕТИЗАЦИЯ ПРИ МАСШТАБИРУЕМОМ КОДИРОВАНИИ ВИДЕОИЗОБРАЖЕНИЙ С ВЫСОКОЙ БИТОВОЙ ГЛУБИНОЙ |
摘要 |
The precision of up-sampling operations in a layered coding system is preserved when operating on video data with high bit-depth. In response to bit-depth requirements of the video coding or decoding system, scaling and rounding parameters are determined for a separable up-scaling filter. Input data are first filtered across a first spatial direction using a first rounding parameter to generate first up-sampled data. First intermediate data are generated by scaling the first up-sampled data using a first shift parameter. The intermediate data are then filtered across a second spatial direction using a second rounding parameter to generate second up-sampled data. Second intermediate data are generated by scaling the second up-sampled data using a second shift parameter. Final up-sampled data may be generated by clipping the second intermediate data. |
