Supporting timely suspect investigations with automated person searches in video footage

Police agencies are still relying on human eyes to find suspects in videos, or to connect identities found in different media.

Cognitec's FaceVACS-DBScan LE technology greatly reduces the time and money spent on such investigations. Hours in manual viewing can shrink to a few minutes of analyzing automated search results.

More than ever before, crime investigators receive photo and film material from a variety of sources, ranging from grainy CCTV footage to high-resolution movies and images. Not all materials are suitable for automated face recognition, but matching algorithms are ever advancing to handle lower-quality images.

FaceVACS-DBScan LE imports still images and video material, finds all faces, and clusters the appearances of the same person, even across multiple media files, tracking their times and locations.

Investigators can open the original video material, and find persons near the subject who might be connected to the crime. A click on another face produces all appearances of this person and opens new search paths.

Any image of a face, regardless of its origin, can be selected for comparison against facial image databases. The software produces a candidate list of possible matches, sorted by match probability.

Investigators can choose to work with smaller, local image databases for quick searches in videos and for instant candidate lists, but can also receive—within seconds—matches from central databases that store millions of images.

Furthermore, they can make use of various tools to inspect image pairs and determine their similarity. In accordance to laws and best practices, face recognition results have to be evaluated by human experts, and only serve as a supporting measure to other investigative methods.

Face recognition match results can quickly narrow down a search trail. Let Cognitec technology help you increase the speed and accuracy of criminal investigations!
