SYSTEMS, METHODS AND BITSTREAMS FOR FEATURE CODING FOR MACHINE APPLICATIONS WITH BIT-SHIFT

Abstract:

Systems and methods are provided to improve encoding and decoding of video in a system for feature coding for machines (FCM). At an encoder site, a right shift operation is performed on tensors of feature maps representing the video signal, removing n least significant bits from each tensor. This reduces the required bandwidth of the resulting encoded bitstream. At a decoder site, a left shift operation is performed on the decoded and reconstructed tensor values to restore the values of the most significant bits of the tensors while replacing the removed LSBs not considered critical to a machine task with zeroes.
