How Forensic Video/Image Enhancement Can Help Investigators?

Video/Image analysis is a crucial part of forensic analysis. It is the scientific examination of videos and images that are recovered from a digital device during the investigation. Examination of video/image evidence involves comparison and evaluation of its authenticity. A major part of forensic video analysis and forensic image is video forensic enhancement, which is a process of keeping the events clear and use of non-destructive events to preserve the integrity and pixel quality of the video/image evidence. A video can be enhanced irrespective of its recording time. The success of video enhancement is directly proportional to techniques and tools of enhancement, resolution, and frame rate of the video. 

The science behind video forensic enhancement

The forensic enhancement process is not something as simple as zooming the video recovered from a video surveillance system. Zooming in on a video messes the quality of the pixels. Pixels are small boxes of color that together form the entire picture. When a picture is expanded, each pixel gets expanded thus degrading the quality of the frame. Effective enhancement is possible with the right tool and technique.

How does it help investigators?

The video enhancement process allows the investigators to see an event in a video as it occurred. It helps the litigators to see the events clearly which are difficult to understand because of darkness or excessive movement. It helps the investigators to capture the event from a poorly maintained or poorly positioned video.

  • Original video quality

 

If a video is too dark, a color correction process is done to match the brightness of the scene and get a clear view. The brightness should not overpower the video obtained from a digital video surveillance system

  • Sharpening 

 

Sharpening the video makes the edge of the video more distinct and clear. it gives details to the subject in the video.

  • Video stabilization

 

When the video has too much movement, it becomes difficult for the investigators to see what is happening. When the video is not stable and has too much movement, it might get rejected by the litigators. The video stabilization technique reduces the amount of movement in the video and produces the most possible playback.

  • Masking

 

This process covers the face of a witness or law enforcement officer to protect them from getting revealed.

  • Interlacing

 

This technique is used to capture images in an analog system. It is a technique that combines two TV fields to produce a single frame video.

  • Demultiplexing

 

This is also a video enhancement technique that allows isolation of each camera. It is used to display images of multiple cameras simultaneously.
