Video & Image Forensics
In today’s world, the presence of video evidence continues to grow with cameras popping up seemingly everywhere. CCTV cameras record all the events of our day to day lives, in-car cameras log the daily commute or a traffic stop, and the use of body worn video and cell phone video has exploded over the past few years. How do we know we are getting the best video data from all these devices? Enter video forensics. Through video forensics, we can clarify images and video to help view details previously unseen. With multiple different camera angles, we can show the timing of events in a scene and even make sure they are synchronized so the playback of the video is an accurate representation of the event. In other cases, we can authenticate video or images to determine if the evidence has been tampered with or altered. We can conduct comparisons of different images and video to match or exclude subjects and/or objects recorded by the camera. If your case has visual evidence, then video and image forensics can help show you the truth.
By using the science of individualization, or the theory that everyone or everything has some unique characteristics, it is possible to compare a questioned image to a known image and potentially determine the relationship between those two items. This applies to video data as well, as video is nothing more than a series of still images displayed at a given number of images per second.
Forensic Image Comparison has many practical applications both for prosecution and defense. Some common items/things we can use for comparison:
- Vehicle dents, damage, bumper stickers, headlight patterns and objects in or on the vehicle.
- Details in clothing such as fabric patterns, logos, creases/seams and clothing construction.
- A person’s tattoos, hair shading, ear and facial structure and scars.
- Determining the location the video was recorded by comparing the surroundings captured in the video to a known environment/location.
- Identify markings on a person, vehicle, or other subject matter.
Video and Image Enhancement is the process of making details in recorded visual evidence clearer and easier to see. Enhancements can include correcting aspect ratio, decreasing visual noise, increasing the brightness of dark video, among other techniques.
With the proliferation of CCTV and Cell Phone video, often times video evidence of a crime is not in the best quality. If your video is blurred, too dark, too light, or has other issues we can employ multiple different methods to clean up your image.
