It's been a busy fall season, traveling the country and training a whole bunch of folks. Over a lunch, the group I was with asked me about a case that's been in the news and wondered if we'd be discussing how to conduct a comparison of headlight spread patterns. That lead us down quite the rabbit hole ... Comparative analysis assumes a "known" and compares it to an "unknown." It's important to

"Is it forensically sound?" I've heard this question asked many times since I began working in forensic analysis many years ago. Me being me, I wanted to know what it meant to be "forensically sound." Here's what I found as I took a journey through the English language. "Forensically." The root of this is "forensic." The root language for the English word "forensic" is the Latin "forensis."

I had an interesting evening. A friend sent a link to a YouTube video, a recorded webinar for a "video analysis" product. I'll admit. I was curious. I watched it. Below is my commentary on what I saw. The presenter outlined his workflow for working with video from a few different sources. The presentation turned to the difference between how Direct Show handles video playback vs. what's actually

I've been in the "video forensics" business for quite some time now. I've seen enough to notice trends in the industry. I've seen people come and go.

In my state - Nevada, for example - to the extent that Daubert espouses a flexible approach to the admissibility of expert witness testimony, the Supreme Court of Nevada has held it

Eliminating repeating pattern noise from images has been a pain for forensic analysts for quite some time. There are tons of freeware apps and plug-ins ranging in price from inexpensive to cost prohibitive Some of their limitations include: they only work on images, their reliability is spotty, you must document your work without quite knowing how the tool is doing what it's doing. Imagine

Many companies have made the decision to cover the interior of their establishments with as few cameras as possible. They do this with 360 degree camera, big fisheye lenses, or a combination of the two. They get to check the box of having CCTV. You get to try and fix this mess back in the lab. In this case, the ClickIt DVR allows the user to segregate camera views and output individual
