Device interface information for high-speed collation using holographic optical correlation

2nd edition, December 2022

This Ecma standard specifies the device interface information and requirements for high-speed image retrieval and collation using holographic optical correlation based on shift-multiplex recording of coaxial holography.

This standard specifies:

  • operating environments
  • holographic optical correlation
  • holographic optical correlation system
  • recording information for hologram database creation
  • readout information for collation
  • report information.

This standard is mainly used in professional fields, especially high-speed movie picture retrieval system to detect illegal and/or specific pictures.
