Abstract
A video is first partitioned into video objects. If the video is uncompressed, then the partitioning is done with segmentation planes. In the case where the video is compressed, a demultiplexer is used for the partitioning. Over time, shape features are extracted from each partitioned object. The extracted shape features are combined to determined a temporal resolution for each object over time. The temporal resolutions are subsequently used to encode or transcode the video objects as an output compressed video.
Claims19
A method for coding a video, comprising:
- partitioning the video into a plurality of objects;
- measuring, over time, differences in shape of each object to determine a plurality of shape features of each object;
- combining, the plurality of shape features to determine a temporal resolution for each object;
- and
- coding each object according to the corresponding temporal resolution of the object.
