More Real Than Real: a Chat About Deepfakes with Dr. Cecilia Pasquini (University of Trento)

Deepfakes and computer-generated images have been around for a few years now, and they’ve become quite popular. We’ve recently authored an article in the Evidence Technology Magazine about the challenging task of Dealing with deepfakes. Much like it happens for cryptography-vs-cryptanalysis, a fight is going on here between those developing advanced neural networks, capable of creating more and more realistic fakes, and those aiming at detecting them. This fight is mostly guided by researchers, but video forensic analysts and everyone dealing with forensic image analysis are necessarily involved, since they may soon have to face deepfakes in their investigations!

Amped FIVE Does Not Use A.I. And Implements Forensically Safe Algorithms to Enhance Video Evidence

TL;DR

In recent days, following the media attention on the Kenosha Shooting trial (“STATE OF WISCONSIN – VS – Kyle H. Rittenhouse”) in which Amped FIVE has been used for evidence analysis, a previous article on this blog about the use of Artificial Intelligence on image and video forensics has been misunderstood and instrumentalized.

The applicability of image interpolation and image enhancement at large as evidence in court has been discussed, sometimes without the needed in-depth knowledge of the field.

In this article, we will clarify some very important concepts related to forensic video analysis at large and Amped FIVE.

1) Amped FIVE does NOT use Artificial Intelligence

Amped FIVE has been designed specifically for evidentiary use. It does not use Artificial Intelligence: image and video enhancement in Amped FIVE are implemented in a forensic workflow based on carefully selected algorithms that guarantee reliability, repeatability, and reproducibility. Thanks to this, Amped FIVE has become widely accepted as the standard tool for forensic image and video analysis, being used in 100 countries worldwide.

2) Interpolation DOES NOT TAMPER with the image

We need interpolation to show things as they are: interpolation is not only used to “zoom on” an image, but it is an essential part of the creation and display of a digital photo or video. Interpolation does not add image information, but improves visualization of image data 1,2,3. Questioning the general acceptability of interpolation means questioning the acceptability of images and videos as evidence.

3) Image enhancements performed by a competent analyst with the right tools are INSTRUMENTAL FOR COURT USE

An analyst with the right tools, technical preparation, and workflow can enhance the image in a way that can help the trier of fact and be accepted in court. Image enhancement is a fundamental part of forensic video analysis and it’s the duty of the forensic video analyst to properly enhance images and videos to give a more accurate representation of the scene, compensating, when possible, the imperfections introduced by the image generation process.

We hope this new take on the argument will help to better comprehend the topic and will clarify some of the misinterpretations of the original post. And if you want to learn more on these topics, please keep reading!

One of the biggest challenges in Forensic Video Analysis (FVA), is the restoration and enhancement of motion blur. In this latest ‘How To’ article, published on Forensic Focus, David Spreadborough returns to Amped FIVE and takes us through one of this year’s new filters, Variable Motion Deblurring.

Learn how the filter works to turn blurred noise into restored and actionable data.
