Enhancing Videos for Forensic Purposes - How do we do it?

The objective of Forensic Video Enhancement is to clarify or enhance the events as they occurred. This is done using non destructive techniques to preserve the video evidence integrity, and pixel quality.

- Scaling/Pixel Interpolation: Re-size, or scale an image or video to a larger resolution to further identify suspects.

- Sharpening: Enhances the edge contrast of an image or video.

- Stabilization: This is most common today with smart phone video evidence. It reduces the amount of movement from the user that created the video evidence.

- Frame Averaging: Increase the quality of the image by combining data from surrounding frames as well as a better signal to noise ratio in your images or videos.

- Speed Reduction: Decrease the original playback of video evidence to view the events as they occurred in more detail.
