Spatial-temporal forensic analysis of mass casualty incidents using video sequences

Area of Science:

• Forensic Science
• Digital Forensics
• Emergency Management

Background:

• Mass casualty incidents (MCI) require effective forensic analysis for understanding events and improving future responses.
• Traditional methods for analyzing MCI evidence can be time-consuming and may not fully capture the dynamic nature of events.
• Video footage from incident sites offers valuable data but requires systematic processing for forensic use.

Purpose of the Study:

• To introduce DIORAMA, a novel system for forensic analysis of mass casualty incidents (MCI) utilizing video sequences.
• To enable efficient review and understanding of on-site video evidence for investigators.
• To improve the analysis of rescue operations and enhance training procedures for MCI response.

Main Methods:

• Development of the DIORAMA system for processing video sequences from MCI sites.
• Automatic annotation of video data with metadata, including capture time, camera location, and viewing direction.
• Implementation of a visual interface for investigators to access and review relevant video clips.

Main Results:

• The DIORAMA system facilitates automated metadata annotation of video evidence.
• Investigators can utilize a visual interface to efficiently locate and review video clips pertinent to specific areas of interest.
• The system provides enhanced comprehension of rescue operations during mass casualty incidents.

Conclusions:

• DIORAMA offers a robust framework for video-based forensic analysis of mass casualty incidents.
• The system improves the efficiency and effectiveness of MCI investigation by leveraging annotated video data.
• Enhanced understanding derived from DIORAMA analysis can lead to significant improvements in MCI response training and protocols.
