Compact Descriptors for Video Analysis: the Emerging MPEG Standard
This work addresses the need for interoperability in video analysis applications, but it is incremental as it builds on existing standardization efforts.
The paper describes the ongoing MPEG-CDVA standard, which aims to define a standardized bitstream syntax for video analysis applications, and reports the performance of techniques that reduce descriptor size and improve video representation ability.
This paper provides an overview of the on-going compact descriptors for video analysis standard (CDVA) from the ISO/IEC moving pictures experts group (MPEG). MPEG-CDVA targets at defining a standardized bitstream syntax to enable interoperability in the context of video analysis applications. During the developments of MPEGCDVA, a series of techniques aiming to reduce the descriptor size and improve the video representation ability have been proposed. This article describes the new standard that is being developed and reports the performance of these key technical contributions.
