This article discusses new tools available to crime investigators and analysts to process videotaped evidence.
Abstract
The widespread availability of high-speed desktop computers has made it possible to process videotaped evidence and for it to be affordable and accessible to police agencies that could not consider it before. Digital video analysis can preserve evidence more effectively than can the previous analog method. It is also crucial to obtain the original of the videotape recording to be processed. Analysts must also use software designed for forensic video analysis. A proper forensic video setup captures the entire frame and renders detail from video images. An image stabilization feature can fix on a small region in the image and adjust each successive frame so that this point appears to remain relatively motionless. Another desirable software feature is frame averaging. Finally, a full-blown turnkey system will produce the vest video evidence for most users. Photograph
