ADAPTING QUANTIZATION WITHIN REGIONS-OF-INTEREST |
摘要 |
A device comprising: an encoder for encoding a video signal representing a video image of a scene captured by a camera, and a controller. The encoder comprises a quantizer for performing a quantization on the video signal as part of said encoding. The controller is configured to receive skeletal tracking information from a skeletal tracking algorithm relating to one or more skeletal features of a user present in the scene, and based thereon to define one or more regions-of-interest within the video image corresponding to one or more bodily areas of the user, and to adapt the quantization to use a finer quantization granularity within the one or more regions-of-interest than outside the one or more regions-of interest. |
