The Image Generation Model (Cheat Sheet Included!)

by Martino Jerian, CEO and Founder of Amped Software

In a nutshell: a digital image is created by a sequence of physical and digital processes that ultimately produce a representation of light information in a specific moment in a specific place, as a sequence of 0s and 1s. The technical limitations of the imaging system will introduce some defects that will make the image different compared to the original scene, and often less intelligible during investigations. The image generation model aims to understand how these defects are introduced, and in which order to correct them in the proper sequence and obtain a more accurate and faithful valid representation of the scene.

A Survey on the Industry Trends

The world seems to rapidly change these days, and so we thought to launch a new survey to understand where our industry is and where it is going. We called it “The State of Video Forensics 2022”.

Last year we did a quite long and technical survey dedicated to our users (you can read here some of the most interesting insights); this time we wanted to widen our audience and make it open to everybody who works on image and video evidence, even the few unlucky ones who are not (yet? 😉) using our software. It’s also much faster to fill, as it should require just 5-10 minutes of your time.

The survey will be open until September 13th, 2022, we’ll then summarize the key findings and present the results at the Amped User Days and in a future post on this blog. All data will be shown anonymously. 

It’s quick and easy, and the results could be useful for you as well. Thanks for your cooperation!

Raising Awareness on Video Evidence at the European Parliament

Last week was pretty amazing. I’ve been traveling for business for the first time after more than two years since Coronavirus. While my colleagues had attended several events,  I’ve not been around very much. I relied more (maybe too much) on what modern technology had offered to us.

However, there are some things that it is better to do in person. Stakeholder engagement is instrumental in order to deal with the institutions: particularly the EU ones. 

And so, I traveled to Bruxelles where I visited the European Parliament for the first time. On may 17th I had the honor to organize the institutional meeting “Video Evidence Analysis During Investigations: Raising Awareness to Grant Security and Justice Through Science”.

Video Evidence: Don’t Take It For Granted!

In the past years, policymakers dedicated a lot of attention to cybersecurity, artificial intelligence, and privacy, especially in relation to video surveillance and public safety. While these are very important topics, I think we need to also dedicate some attention to the more fundamental issues that often go unnoticed and relate to the proper understanding of image and video evidence, both during investigations and in court.

From Mechanical Engineering to Forensic Video Analysis: The Experience of Alan Michaelis

Alan is the owner of ALCAR Multimedia; while he transitioned relatively late to the world of forensic video analysis, he attended a lot of different training classes and became soon very passionate about the topic. Read on to see what first sparked his interest in the field and what are the most important aspects of training and education.

A Survey on Video Evidence: The Highlights from the Amped User Days 2021

In April 2021, we had our second Amped User Days, an event reserved for our users which put together 298 people from 34 different countries.

While we are in constant communication with our users, we wanted to get a bird’s eye view of the industry and behaviors with video evidence so we took the opportunity to ask them to contribute to our study by replying to a few questions.

I thought some of the highlights from the survey were quite interesting, so I’ll go over them in this post.

Read on to see some of our questions and replies from our users.

Who’s Using Amped Software?

Very often when potential customers are researching products, a pretty common question they ask us is “who’s using your software?”. We take privacy and security very seriously, and we don’t publish customers’ names or logos without their permission. This permission, for public safety and national security organizations, is actually quite hard to get by official means or takes way too long. So we are rarely nominating users and cases explicitly.

In this post, we are sharing some aggregated data you may find interesting. It is being published in December 2021, so if you are reading this later, the numbers will likely be higher.

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!
