Advanced File Information – A Closer Look!

In the recent Amped FIVE Update (Rev. 9010), there were some big additions to the advanced “File Info”.

The updated tool has already received high praise from regular users who can now do all their frame, stream, hex and format analysis from within the same application – Amped FIVE!

It’s time therefore to take a much closer look at this new and powerful functionality.

Amped FIVE Update 9010 Part 2: Filter Updates and Interface Enhancements… too much for one post!

Amped FIVE Update 9010 continues…this is the second post relating to our very big Amped FIVE update launched a few days ago. In case you missed Part 1, click here.

Filter Updates

Measure 3d

When setting a reference measurement, the most common mistake is to get your line in the wrong direction! This then reverses the measure result.

Under the “Reference” tab, we have made things easy for you.

Amped FIVE Update 9010 Part 1: Resize 1:1, Perspective Aligner, Block Difference, Frame Analysis

Many months of filter development and product expansion have resulted in a very big update to Amped FIVE!

As a result, we created two blog posts on this update. This is the first post. The second will come soon…

I have said it before, and I’ll say it to you again now… most of these development ideas have come from you, the user. If you suggest an idea, it goes onto the list. That list drives the updates. We are committed to providing you with the most advanced software for all of your needs in image and video forensics.

New Filters

Resize 1:1

Calibrating an object to a known scale is important in fingerprint, footwear mark and other analysis and comparison tasks. “Resize 1:1”, located under the “Edit” category, now enables you to use the scale shown in the image to present the image at the actual size.

Amped Authenticate Update 8782: Enhanced PRNU, LCD Recapture Detection and many more filter improvements

At Amped Software we are continually researching new methods to help you in your analysis. Designing, testing and then implementing new features and filters is a continuous process. When complete, we get these out to you as soon as we can.

In this post, I will be introducing you to some of the latest developments in Amped Authenticate.

For those new to this blog, or the software, Amped Authenticate is a software package that enables you to conduct forensic image authentication and tamper detection on digital photos and documents. Today, digital images are key sources of evidence in criminal activities. But the creation and manipulation of those images is relatively easy to do, so it is vitally important that images being used as evidence are what they say they are. Amped Authenticate is the only software in the market that includes, in one single and easy to use package, all the scientific tools and functions necessary to discover tampering on an image or determine originality, and to verify if a picture has been generated by a specific device. 

This update includes some very big improvements and additions.

Fourier

Amped FIVE users will be aware of how powerful the Fourier domain is in identifying and then removing frequency noise in images. This frequency noise can also be used to identify signs of LCD Recapture. As a result, this filter is now included in Authenticate.

Amped FIVE Update 8678: Faster Redaction and Automatic Pattern Removal

Well, here we are again, with another exciting update to Amped FIVE.

Before we dive in and take a closer look at all the developments, I want to say a quick thank-you to the users of Amped FIVE who have suggested refinements and requested new functionality to help them and others in their Forensic Image and Video work. We develop this software for you. If you need it, we will deliver it!

OK, let’s get to it!

Dynamic Tracking

It is one of those tasks that, in small amounts, can be quite enjoyable. However, when you are constantly spotlighting or hiding people, it quickly becomes tiring. That’s when mistakes are made, and it’s easy to miss something that could be detrimental in an investigation. Dynamic Tracking has been in the Selection box for some time but it has received a very powerful ‘upgrade’.

Amped FIVE Update 8222 – Adjustment Filters, Program Options and Much, Much More!

It’s Amped FIVE update time again!

With so much to get through, let’s start with some new and exciting filters. Not one, not two….. but six new filters in the Adjust Category. Yes – Six new filters designed specifically to restore color or illumination to an image, and improving those taken with High Dynamic Range.

Parametric Curves

This filter gives you very precise control over the four portions of the luminance range. As you adjust the sliders, the curve will move accordingly, and a shaded area will appear in the Curve graphic. This will show you the maximum or minimum adjustment available.

Amped FIVE Update 8006 – Filter Search, Case Notes and Much More

We never stand still here at Amped!

The latest update for Amped FIVE (8006) is now available to download.

I keep on saying this, but many of the updates have come directly from user suggestions. We listen to you and then put your suggestions to the test! If all goes well, then your help goes to benefit everyone. Some other points that we take seriously here at Amped are keystrokes, mouse clicks, and mouse movement. If we can find a way to reduce these then we do so… and you will see a few examples in this update.


Interface Improvements

Sometimes, finding that filter can be tricky if you can’t remember what category it’s in. We now have a Quick Search bar within the Filters Window. Start typing the name of the filter and the suggestions will be listed alphabetically.

Case Notes, information, or any text relating to your investigation can now be entered directly into the Notes Interface.

Notes

This window can be activated by using the Menu, View > Notes. Continue reading

Aspect Ratio – Understanding the Information and Using the Filter

Our initial post on the subject of Aspect Ratio correction detailed the complexities surrounding how an image should be displayed, and the importance of understanding how our digital data has been created. This post will go into the information reported by Amped FIVE and how to use that information to make any necessary adjustments.

Let’s have a recap!

SAR Storage Aspect Ratio: Width by height ratio of the encoded digital video (calculated simply by dividing the width by the height of the actual stored frame).

SAR Sample Aspect Ratio: Width by height ratio of the pixels with respect to the original source. (Information, if available, that is stored within Mpeg4 streams).

DAR Display Aspect Ratio: Width by height ratio of the data as it is supposed to be displayed (information, if available, that is stored within the file or calculated using other values).

PAR: Pixel Aspect Ratio Width by height ratio of the pixels with respect to the original source (like Sample Aspect ratio, but calculated dividing DAR by Storage Aspect ratio).

It’s unfortunate that we have to define two different definitions for the same “SAR” acronym. Different standards and pieces of software use the same acronym, often without explicitly saying if it’s Storage Aspect Ratio or Sample Aspect Ratio.

How are these values displayed and calculated in Amped FIVE?

First up, we have the Quick Info Tool:

Introduction to Aspect Ratio

In the recent Amped FIVE Update (7620), there were a number of enhancements all concerned with the Aspect Ratio of a digital image and the pixels that make up that image. In this series of posts, I will endeavor to simplify this subject with the aid of the new filters and features in Amped FIVE.

When developing Amped FIVE, a huge importance is placed on user flexibility. Can it do simple things quickly? Can it utilize advanced filters and algorithms? Can a user grow with the software to conduct higher level analysis and enhancement techniques as their skill level increases?

As a result, there are very few places where a user is restricted from performing a certain technique or applying a specific parameter. It is up to the user, based on their image assessment and the task required, to establish a process and then complete that process using the software.

During the implementation of the Aspect Ratio Filter, this user flexibility ethos was considered and, quite rightly, maintained.

You decide what ‘Output Aspect Ratio’ to apply. You decide how to rescale and what Interpolation method to use. It is up to you, the user, to utilize all the presented information and perform a process, based on that information.

It is, therefore, important to understand the complexities of Aspect Ratio and why the filter works in the way it does.
