Abstract
A method and apparatus for characteristic-based video processing include: in response to receiving a region of a picture of a video sequence, determining a characteristic in the region, the region being independent of other regions of the picture for video coding; determining a class associated with the region based on the characteristic, the class being selected from a plurality of classes; and encoding the region using a parameter set associated with the class, the parameter set being selected from a plurality of parameter sets for video coding at different quality levels.
Claims20
A non-transitory computer-readable storage medium storing a set of instructions that are executable by one or more processors of a device to cause the device to perform a method comprising:
- decoding a compressed video sequence to obtain a parameter set associated with a region of a picture in the compressed video sequence, wherein the parameter set represents a quality level for video coding and is associated with a class;
- and
- decoding the region using the parameter set, wherein the decoded region comprises a characteristic, the characteristic comprises a content characteristic associated with video contents in the region, and the content characteristic comprises at least one of a scene representing an incident in the region or an environmental event in the region.
An apparatus, comprising:
- a memory configured to store instructions;
- and
- one or more processors coupled to the memory and configured to execute the instructions to cause the apparatus to:
- decode a compressed video sequence to obtain a parameter set associated with a region of a picture in the compressed video sequence, wherein the parameter set represents a quality level for video coding and is associated with a class;
- and
- decode the region using the parameter set, wherein the decoded region comprises a characteristic, the characteristic comprises a content characteristic associated with video contents in the region, and the content characteristic comprises at least one of a scene representing an incident in the region or an environmental event in the region.
A computer-implemented method, comprising:
- decoding a compressed video sequence to obtain a parameter set associated with a region of a picture in the compressed video sequence, wherein the parameter set represents a quality level for video coding and is associated with a class;
- and
- decoding the region using the parameter set, wherein the decoded region comprises a characteristic, the characteristic comprises a content characteristic associated with video contents in the region, and the content characteristic comprises at least one of a scene representing an incident in the region or an environmental event in the region.
