Many times we have faced an issue where a blurry image can be very useful evidence. Here, the usage of forensic video analysis software, picture enhancement software, image authentication software, forensic multimedia software, and forensic image processing software acts as helpful tools to identify the suspect in a crime.

As we know, video is extremely vital and influential in the realm of crime, social media and digital marketing. It's mostly used to assess the credibility and authenticity of digital evidence. The forensic analysis of audio and video is carried out in order to enhance speech intelligibility and sound audibility in the recordings.



What is Forensic Video Enhancement?

Forensic video enhancement is the process of analyzing digital photos that have been utilized as evidence. By using, forensic video analysis software, we can enhance digital video in various formats, including CCTV systems, cell phones, and dashcam footage.

Here are a few things to think about when doing forensic video analysis. Please have a look at it.

· The video's size and resolution
· Evidence of the video conversion (from original video format)
· Editing or fraud evidence
· Video frame rate, codec, and other critical characteristics are determined.
· Metadata or Exif Data Analysis

The following are the most common and accurate video enhancement tools or techniques used during an investigation, such as:

· Scaling/Pixel Interpolation:
To identify suspects more clearly, resize or scale a picture or video to a higher resolution.
· Sharpening:
It improves the edge contrast of a video or an image.
· Warp Stabilization:
It reduces the movement from the user, who created the video evidence. It is commonly used with video evidence from a smartphone.
· Shadow and Highlight Adjustments (Exposure):
It reveals minute details in the shadow and highlights sections in the image.
· Frame averaging:
Enhance the image quality by merging data from nearby frames and achieving a higher signal to noise ratio (SNR).
· Speed Reduction:
Reduces the initial playback speed of video footage to get a better perspective of the events as they happened.
· Pixel Aspect Ratio Calibration:
Changing the ratio that indicates how a pixel's width corresponds to its height in a digital image.
· Reverse Projection:
Reverse projection is an easy and quick method of determining the size of an object or person of interest.
· Color Correction:
This tool more appropriately describes the tone and color-correction capabilities found in most non-linear video editors.
· Demonstrative Video Exhibits:
This technique includes the digital viewing of video or physical exhibits.
· Motion Tracking:
It allows computer visuals to be inserted into live-action footage with the appropriate scale, position, orientation, and motion associated with the objects in the shot.
· Photogrammetry:
This method is all about taking precise measurements with the help of photographs, particularly aerial images. It is very important in forensic image processing.


Conclusion

I hope that the above brief of Forensic video enhancement and related methodologies was helpful. The tiniest nuances can have a big impact on the outcome of a case when it comes to forensic video evidence. As a result, it's critical for authorities to do everything possible to identify a suspect in a crime so that they can figure out exactly when and how it happened.
