Forensic Video Analysis Using dVE

Forensic video analysis cannot, in general, be conducted by observing recorded video at nominal 30 Hz video rates.  The human 6-Bit Vision intrascene dynamic range problem can, conceal important dynamic information of forensic interest. Important transients persisting only a few video image frames can be missed altogether. The Visibility Laboratory forensic video analysis protocol using dVE is illustrated in the graphic.  It begins with the extraction of individual frame images from the entire video or from video temporal segments of interest.

The individual frames are subsequently dVE processed and carefully examined individually in sequence.  Transients are identified and candidate image spatial segments, Regions of Interest (ROIs), are identified and subjected to more specialized algorithms in the dVE suite. Image processing gain can be adjusted to improve the visibility of critical detail. Full-frame or ROI dVE Video can be produced using the individual dVE processed image frames.  Observation of dVE Video played at normal video rates can further advance forensic analysis.
