ISO/IEC 30137-4 is the fourth part of an international standard that covers the use of biometrics in video surveillance systems.
ISO/IEC 30137-4 establishes requirements for the annotation of humans, human faces, as well as other body parts, and arbitrary objects appearing in imagery. It specifies the metadata to be inserted in a video stream and encoding of full, procedures for different annotation of known and unknown subjects, as well as partial spatial and temporal ground truth information for:
Note: ISO/IEC 30137-4 does not specify the encoding of video data.
ISO/IEC 30137-4 on Use of biometrics in video surveillance systems is useful for:
Considerable improvements in the performance of automated face recognition (AFR) have resulted in applications such as automated border controls, where facial images encoded in e-Passports are compared with the face presented by a traveller at a control point. The success of these first-generation AFR systems has encouraged suppliers to consider other applications.
ISO/IEC 30137-4 provides guidance on the use of biometric technologies (primarily automated face recognition) in video surveillance systems (VSS) for several scenarios, including the real-time operation against watchlists and post-event analysis of video data. It includes guidance on the selection and placement of cameras through to system specification, testing and maintenance.
ISO/IEC 30137-4 addresses the annotation of human beings. It supports several applications, including people counting, stating the number of people present in a location, stating the number of people traversing a given point or volume, stating population density (e.g., in crowds), measurement of crowd densities performance of crowd behavioural analyses.
ISO/IEC 30137-4 also helps the users for automated detection and tracking, in a way for automated enrolment (addition) of subjects to a watchlist, exhaustively or after behavioural analysis and detection of subjects, and parts of subjects (e.g. faces), etc.
ISO/IEC 30137-4 includes annotation of the information such as imaging type, when the subject appears in the video (start time) and when they leave (end time), subject interactions with other subjects and groups, subject interactions with other video elements (bag, car, etc.). Standardized annotation helps the users for evaluation, research and development, and operational deployment.
