Feature Compression for Machines with Range-Based Channel Truncation and Frame Packing

Abstract:

This paper proposes a method that enhances the compression performance of the current model under development for the upcoming MPEG standard on Feature Compression for Machines (FCM) [1]. By truncating low-activation feature channels and signaling these truncations in the bitstream, the method reduces bitrate while preserving task accuracy. Experimental results show an average BD-rate reduction of 10.59% across datasets and tasks, demonstrating gains in bitrate efficiency.
