Abstract
A method for accelerating inference for compressed videos, the method comprising: extracting (220) features for a frame comprised in a compressed bit stream; generating (230) a partition map comprising zero or more partitions; determining (240) a total area covered by the zero or more partitions; comparing (250) the total area covered to a threshold; if the total area covered exceeds the threshold, generating (260) a motion vector map and warping (290) the feature maps based on the motion vector map.

A method for accelerating inference for compressed videos, the method comprising:
- extracting features for a frame comprised in a compressed bit stream;
- generating a partition map comprising zero or more partitions;
- determining a total area covered by the zero or more partitions;
- comparing the total area covered to a threshold;
- and,
- selectively either (a) generating a motion vector map and warping the feature maps based on the motion vector map or (b) performing a full inference for the frame, depending on whether the total area covered exceeds the threshold.
A viewing apparatus for accelerating inference in video decompression, the viewing apparatus comprising:
- a feature extraction circuit configured to extract features for a frame comprised in a compressed bit stream;
- a partition map generating circuit configured to generate a partition map comprising zero or more partitions;
- a total area determination circuit configured to determine a total area covered by the zero or more partitions;
- a comparing circuit configured to compare the total area covered to a threshold;
- a motion vector map generating circuit configured to generate a motion vector map responsive to the comparing circuit determining that the total area covered exceeds the threshold;
- and
- a warping circuit configured to warp the feature maps based on the motion vector map responsive to the comparing circuit determining that the total area covered exceeds the threshold.
