Abstract
A method and apparatus for video encoding with multi-level regions of interest is disclosed. According to the present invention, a target frame in the input video data is configured into multiple-level region-of-interest (ROI) regions. Each target higher-level ROI region is located within one target lower-level ROI region. The multiple-level ROI regions are then encoded according to a plurality of quality levels, where at least two different quality levels are applied to two different multiple-level ROI regions respectively.
Claims16
A method of video encoding comprising:
- receiving input video data comprising a sequence of frames;
- configuring a target frame in the input video data into multiple-level region-of-interest (ROI) regions, wherein each target higher-level ROI region is located within one target lower-level ROI region;
- and
- encoding the multiple-level ROI regions according to a plurality of quality levels, wherein at least two different quality levels are applied to two different multiple-level ROI regions respectively.
An apparatus for video encoding comprising one or more electronic circuits or processors arranged to:
- receive input video data comprising a sequence of frames;
- configure a target frame in the input video data into multiple-level region-of-interest (ROI) regions, wherein each target higher-level ROI region is located within one target lower-level ROI region;
- and
- encode the multiple-level ROI regions according to a plurality of quality levels, wherein at least two different quality levels are applied to two different multiple-level ROI regions respectively.
