REFINEMENT OF RECONSTRUCTED FEATURE TENSORS

原文（中文）

Disclosed herein are systems, methods, and instrumentalities associated with the refinement of feature tensors. A decoding device as described herein may obtain, from a bitstream, multiple feature tensors associated with a picture, wherein the multiple feature tensors may be compressed from respective original feature tensors associated with the picture. The decoding device may determine a single set of statistical parameters associated with the original feature tensors, restore the multiple feature tensors obtained from the bitstream to derive a set of restored feature tensors, and refine the set of restored feature tensors based on the single set of statistical parameters. The decoding device may then perform operations associated with the picture using the refined set of restored feature tensors. An encoding device as described herein may determine multiple feature tensors associated with a picture, determine a single set of statistical parameters associated with the multiple feature tensors, and encode the multiple feature tensors and the single set of statistical parameters into a bitstream.
