Law Enforcement

Photographs and videos are increasingly the subject and the tools of law enforcement.  Long-gone are the days when only mug-shots and crime scene photos, on paper, were examined for clues and used as evidence.   Today, increasingly large numbers of digital photographs and videos are examined and preserved by law enforcement agencies.  These visual objects include: images of crimes taking place, images of objects which have been stolen, images of intellectual property which is to be protected.  In some cases, the images are in fact the crime itself, such as in the traffic of images of child abuse.

The challenge is to find pertinent visual evidence in these hugh volumes of data.  The products and solutions of LTU technologies are designed to help investigators work more efficiently in examining these high volumes of data, and to elp them achieve what otherwise would be humanly impossible:  out of millions of images, finding the pertinent images which might bring additional clues to a current investigation.   Key features used by law enforcement are:

• similarity search
• clone matching
• file triage (sort and display large image sets by type:  document, photo)
• image metadata exploitation
• classification (portrait detection; pornography detection)
