Meet us at Digital Experience 2013

We are proud to announce that next week we’ll be present at Digital Experience 2013, the biggest conference for digital investigation professionals in the Netherlands.

The conference, organized by our Dutch partner Data Expert, will be held at the Hotel Houten, nearby the center of Utrecht, Netherlands, on October 2nd.

We’ll present two workshops:

Forensic Video Analysis with Amped Five: enhancement of images and videos during investigations.

The session will introduce the audience to the complex theme of forensic video analysis and enhancement. The lesson will be based  on the evaluation of around 10 different cases which range from CCTV restoration, latent fingerprint enhancement and measurements of subjects done directly on the crime scene photos.

Forensic Photo Analysis with Amped Authenticate: originality, manipulations and camera ballistics.

The session will present an overview of different techniques that can be used for evaluating the originality of a digital picture in a forensic setting. Through several samples, we will explain the basic ideas for understanding if an image is a reliable source of evidence or it has been manipulated, and identifying the device used to generate that image.

See you there?

Calculate camera position from a picture or video

The Measure 3d has been in Amped Five for years, and it’s certainly one of the most reliable and quick ways to calculate the height of a subject or another distance from an image or video.

In the latest version of Five, we have added several improvements, like the possibility to select the layers of calibration lines to show on the picture, and the possibility to draw free hand lines (not constrained by the perspective) to help with the estimation of ground floor points.

In the just released update, we added another useful feature to the Measure 3d filter, which is the ability to automatically calculate the camera position with respect to the ground plane.

Thanks to the calibration of the perspective, once you set the reference measurement, you’ll know automatically the height of the center of the camera optics from the ground.

You can simply read the value from the Camera Position parameter in the Reference tab.


Of course, it’s subject as always to the measure error as any other measure taken with this system, but it can be useful for different purposes.

For example, you may want to verify that a camera has not been moved after an event. Another use for this could be to calculate the position from where a picture have been shot with a digital camera,so you can estimate the position of the photographer relative to the subject.

Amped Five update with user suggested improvements

As a company, we are particularly fortunate to have very innovative and knowledgeable customers. Since the target for what we need to offer keeps moving, we welcome and are grateful for the feedback necessary to correctly aim to hit it. Those of you that know us know that we don’t sit on our products and wait for some cosmic event (or customers with pitchforks and torches at our door) before release new tools; nor are we trying to serve yesterday’s tech as today’s new hotness. The bar is always raised by customer needs.

Today we just released a new version of Amped Five (build 5600). There are several added capabilities and improvements under the hood.

Here you can quickly find what’s new:

  • Video Loader: all video engines support now Unicode (non-Latin character) filenames
  • Video Writer: added support for Unicode (non-Latin character) filenames
  • Sequence Writer: support for optional starting frame number
  • Measure 3d: added the possibility to enable or disable the visualization of different lines
  • Measure 3d: added the possibility to draw unconstrained lines to help with ground point estimation
  • Player Panel: frame type (I,P,B) displayed after frame number, if available
  • Set “hand” cursor for dragging the image
  • Better formatting for documentation and reports
  • Filter documentation fully reviewed and updated

Thank you to all of our customers, with special thanks to George Reis, Catalin Grigoras, Jim Hoerricks and Saverio Paolino for having suggested these (and many other) improvements to our software. We’ll try to keep up with your needs!

See you at LEVA next week.
