Maintaining the original evidence integrity is a key element in the design of Amped Five. In the law enforcement arena, courts, judges, prosecutors, and defense attorneys can sense the weakness of evidence and exclude it if there is any manipulation that has been done. The current judicial trend in admission of digital evidence shows that undocumented or modified files have a strong chance of being excluded. If this is the key evidence in a case, the case is likely to be lost.
With Five, our core philosophy in designing the product is that everything is done by simply applying a filter. This means that no rendering, modifying, altering or disturbing original evidence is done. Whether you are loading a video, exporting a sequence, applying some denoising, selecting frames, taking measurements and so on... This concept of filtering allows for very fast, elegant, and predictable workflow. For each step in the process, every filter takes as input the image or video generated by the previous filter and, after the processing, passes the result to their output filter (if any). You can even modify a filter and see the real time output effects on another one: in this way you can see how modifying some values on a previous filter will modify the final result. This is very effective especially for complex problems and long chains of filters.
Trial and error is often the most common scientific method that is applied in forensic analysis. Experimenting with different filters and settings is done to find the right filter group, settings, or combination of steps to correct unique problems. With most other forensic image processing software, this is a very long process that often must be restarted if one filter has to be changed or results are not optimal; then restarted again should the results of the second (or third or fourth, etc) result prove to be less than ideal. We have designed the architecture of Five with this in mind. Reviewing and modifying any step of the processing is as quick and easy and as simple as replacing, deleting or moving filters anywhere in the chain. In this way Five guarantees speed, effectiveness and scientific rigor.
