A few months ago we launched a pretty bulky Amped Authenticate update with several new filters and features. In this post we’ll explain how the ADJPEG and NADJPEG filters work and how to use them.
When an image is first compressed using the JPEG format, there is a uniformity to the Discrete Cosine Transform (DCT) coefficients throughout the image. If an object is placed into the image and then it is re-saved, there will two different levels of compression.
Creating your own bespoke settings in Amped Authenticate means that you can load specific filters and configurations, depending on the current investigation.
It’s a common issue, you may not need to run everything, all of the time. You may want to reduce the number of filters to speed up an initial preview of many images.
Authenticate allows this through the use of a .aas file.
