Amped has a Chat with Forensic Video Expert, George Reis

We love learning about our users. We are always interested to hear your views about the world of image and video forensics, what your challenges are, and especially finding out about your interest in books, gardening and maybe even dancing!  If you are interested in sharing your story, contact us for a chat!

George Reis, an expert photographer turned forensic image and video expert, and now the owner of Imaging Forensics, tells us how many fruit trees and vegetables he has in his garden and his love for reading and dancing! But he also shares his thoughts about the challenges of DVR systems and what he thinks the future of image and video forensics will look like.

I have known George for many years. He helped us a lot during the development and testing of our tools. Not only did he request a lot of useful features that have been added to Amped FIVE and Amped Authenticate, but he also tested the software thoroughly, reporting bugs and various little details that we had missed during development. To tell you the truth, to implement all the features he asked for means we would need to double or triple our team… but it’s good to be pushed to the limit. Thanks to George and people like him, we have a very rich roadmap for the next few years.


George, tell us a bit about yourself. What is your background and can you tell us about your company?

I am the owner of Imaging Forensics, a company that provides forensic video analysis, photography analysis, and photography. Imaging Forensics also provides training in these disciplines.

Prior to entering forensics, my background was in photography, primarily in the field of photojournalism. I was then hired by the Newport Beach (CA) Police Department as a forensic photographer. My duties expanded into the areas of photographic enhancement and video analysis in the early to mid-1990s, when all security video was analog on VHS tape.

I retired from the police department in 2004 to make Imaging Forensics a full-time venture.

What made you decide to enter the field of multimedia forensics?

I got into forensics in general, and forensic video analysis specifically, by accident. In the late 1980s, I was a freelance photographer and business was slow. I answered a newspaper classified ad for a “police photographer” with the intention of using it to stabilize my income, then returning to the freelance field. But, I found forensics much more interesting and rewarding than I expected.

In 1992 I began experimenting with digital photography and enhancement of fingerprints. And, around 1995, our video producer asked me if I’d like to work on some security camera video and I then took over those duties.

Altered images: The challenge of identifying fake photographs

Fake photographs have been around for almost as long as the camera, but in a digital age of photography, the ability to alter images has never been easier. EU Forensic Video Expert David Spreadborough examines the current challenges surrounding authenticating images.

Thanks to the latest administration in the USA, the term ‘fake news’ has become a popular method of explanation to an event created within social media. The problem is that news agencies and websites find these invented stories and then republish, therefore causing the spread and proliferation of the fake story.

You may have seen this image recently during the G20 meeting of world leaders. Looks like a serious conversation. It may have been, but Putin was never there. Find a picture, create a story, ‘Photoshop’ the picture, then tweet it. The fake news cycle then starts. The more relevant the story, the quicker the spread.

The modification of images to tell a different story is nothing new, it’s been happening since the early days of photography. A popular myth is that it’s a problem caused by the digital age. An example is the photo of The Cottingley Fairies. Although I accept that digitisation has made things a lot easier and a lot more convincing.

Over the past few months, entwined between the ‘fake news’ stories have been several reports of manipulated images appearing in academic studies. It is easy to understand how people can be swayed to change a couple of images to validate a piece of research if it assists in the success of a financial grant. Images in documents used to prove qualifications and images proving the existence of large, wild cats in southern England have also all recently been found to be fake, or maliciously manipulated. When someone fakes an image, it is simply to present an event in a different way than the original moment in time. Continue reading

Using Project Files as Templates in Amped FIVE

People often ask, “How can we speed up the processing of files in Amped FIVE ?” (As if it’s not fast enough :). “Can we create actions/templates?” The answer is yes. Here’s how.

Load a video file. In this case, we’ll load a BWC file from an Axon Body 2 camera.

Then, we’ll rename the processing chain. Right mouse click on the processing chain – Rename Chain.

The Beginner’s Guide to Suspect Height Calculation from CCTV

Otherwise known as ‘The Science of Single View Metrology’

The first common question asked to a forensic video analyst is, “Can you tell me what that license plate is?”. The second question is, “What is the height of that person?”.

It is then the forensic video analyst’s responsibility to analyze the video, assess its suitability to answer the question, process and prepare the images, and then finally use science to provide the answer, based on facts.

Taking a ‘workflow’ approach can often safeguard the user from missing vital information that may be relevant further along in the process.

There are a few different methods to attempt an answer to this height question, with different constraints, reliability, and drawbacks. In this post I will be taking an in-depth look at the technique built into Amped FIVE, using the filter Measure 3d.

What monitor to use?

It’s a common question during training – “What Monitor to use?”

One of the many reasons why people start using software like Amped FIVE is that it installs and runs on any modern Windows PC. There is no need to have huge amounts of hardware or specific configurations. A good, stable setup will work perfectly well.

One of the key purchasing decisions though, when updating or designing a new workstation is the monitor. Some of you may remember that I briefly mentioned monitors in last year’s Advent Calendar: useful tips and tricks in Amped FIVE blog post.

Amped featured in Fraud Intelligence

Alan Osborn, from Fraud Intelligence, writes about the strong interest shown at the Forensics Europe Expo, by the Trieste, Italy-based company Amped Software, whose technology enables the analysis, enhancement, and authentication of images and video. Amped told FI how it’s very easy to alter an image and change the context and the meaning of that image, but hiding the artifacts that are left behind is much harder.
