VIDEO DEBLURRING SOFTWARE

The Untold Secrets of Forensic Video Enhancement

So you are probably reading this blog post because you have been watching too much CSI or because you have tried Amped FIVE on your crappy DVR video and weren’t able to obtain the miracles that you can see on our samples page.

The point is that experts don’t do miracles, they are just scientists. They work with number sequences that incidentally happen to represent some visual information called an image or a signal called a video.

Some people may even wonder if the images on our website’s samples page are fake and they artificially introduced defects on good images in order to show how the software works. They assure you that what you see are results of real pictures or video, most of them have been taken by myself to reproduce typical situations you will find working in forensic cases and with CCTV videos.

Of course, they are not going to put on the web confidential and personal data belonging to real cases that they receive from customers or that they are asked to analyze. They are a professional company, they keep those cases strictly confidential, so they never would appear as samples.

They view more than a few hundred cases every year from customers, but even with the continuous improvement of image processing algorithms, very often they simply look at the video/image and realize that there is nothing to do. The bottom line is this: they are analyzing the picture to get some information (identifying a face, reading a license plate…); if this information is present in the image but not visible because of some defect, within certain limits and with the proper scientific procedure, they are able to recover it and make it visible.

If the information is not there in the original footage, experts cannot (and they must not, since they are in a forensic context and not the photo editing or art world) add it or recreate it.

More than half of the cases that they receive are quickly analyzed and then discarded because the enhancement is not feasible or will not bring any useful result. Without the necessary experience, it is difficult to quickly evaluate the feasibility of a case and very often, potential customers evaluate it giving a completely wrong assessment.

Sometimes a license plate is looking like it’s almost readable, so very little should be needed to make it readable, but actually, it’s not possible to get anything. Other times situations that look hopeless can give amazing results. As a forensic video analyst working every day on multiple cases, it’s very important to acquire the expertise to evaluate the feasibility in a fast manner in order not to waste precious time on activities that will not bring any results.

 

How Audio Enhancement Software Help To Solve Criminal Cases

Technology is amazing. In a very short span of time we have moved from an age of analogue audio and video to digital imagery and sound – and we’re still progressing. With modern devices, we’re able to tune into and pick up even the most subtle tones, such as the echo of a violin string squeaking amid an orchestra.

Unfortunately despite all of our advancement in audio, those working in forensic audio still find themselves in situations where a very important message somehow doesn’t come out the same way it went in. Hence many companies come up with the idea of video enhancement software where enhance CCTV footage helps the end-user to present with the versatile user interface that allows for interactive change of processing parameters and interactive geometry selection.

Masking noises are probably the biggest culprit for many. Not only from the ambient sounds of a room and the surrounding environment, which can make some recordings seem completely useless but from electronic interference in the area that jumbles equipment and creates issues that can’t often be corrected on-site.

Sometimes the interference isn’t recognized until after the fact when it’s too late to correct the issue. Of course, there’s always equipment to fix problems with other equipment; audio enhancement and noise reduction have been used for years to deal with issues relating to interference and masking noises.

Audio enhancement techniques have been useful both in a commercial setting – where lecturers and other speakers can have discussions or dictations cleaned up – or in forensic situations where the actual audio could mean the difference between a conviction or an acquittal.

The equipment used is another roadblock and can drastically distort the quality of a recording. Often problems can be blamed on dated equipment that’s not properly configured but even new, cheaply made equipment or improperly used equipment can create similar problems. Modern audio enhancement techniques can counter the problems that arise from using older analogue equipment or situations where digital recorders were used improperly.
