With the new year comes a new update to Amped FIVE with some exciting new features and a couple of brand new filters!

Timeline

If one of your regular tasks is producing video for presentation purposes, you’ll be excited to know that there is now the option in Amped FIVE to combine multiple video chains together in our new Timeline filter, found under the Link group of filters.

Log-Scale: A Great Ally for Plot Interpretation!

Amped Authenticate users know how important it is to understand the processing history of an image, and they (hopefully!) know that “processing history” does not mean just splicing.
For example, there are cases where the image has been scaled or re-compressed, and
when one of these happen you should be aware of it, as they bring important consequences to the rest of your investigation.

Amped Authenticate offers many tools for processing history analysis under the Global Analysis filter category. Some of these, for example the DCT Plot, the Correlation Plot, and the JPEG Ghost Plot are… plots! They should be examined carefully, because we know that artifacts like a “comb-shaped” DCT histogram strongly suggests double JPEG compression, and so does a JPEG Ghost Plot with multiple local minima. The problem is… sometimes it’s just hard to see these artifacts, because they are “hidden” in the plot!

Consider the image below: at a first glance, its DCT Plot for DCT Frequency 4 seems rather “smooth”, and you could easily overlook it.

Static & Dynamic Tracking: never miss your object(ive)!

Probably, Tip Tuesday aficionados have already understood the trend: we’re alternating tips for FIVE and Authenticate every week. Well… it is true. And it is intentional!

Today we’re showing you some tips about tracking in Amped FIVE. Tracking an object is a basic, yet non trivial operation lying underneath a lot of Amped FIVE filters. You may want to track an object for annotation purposes, e.g. for having a red circle to follow the circled object as it moves. More frequently, you will be using tracking as a part of Local Stabilization, that is used to keep your object of interest static, so that you are able to view it better and effectively average its pixels over multiple frames.

Regardless of the goal, good tracking is essential to the success of your processing. That is why Amped FIVE features several different ways to track your object of interest:

  • Manual tracking
  • Static tracking
  • Dynamic tracking
