Image Science
Photographs hold a plethora of information that is neccesary in determining conclusions. At IRSA, we have the ability to duplicate the lighting and contrast of the site at the time of the accident.
On many cases, we have pulled the metadata in order to find out the time, date, latitude/longitude, the exact camera, exposure, focal length, direction of POV, and a slew of other factors crucial to Reconstruction and Biomechanics.
Above, we see a mere fraction of information that can be collected from an image. Though it may be hard to read, if you look through the extracted data, you will see the creation source of this image.
Additionally, we conduct macro photography to be able to capture particle-like material. This could help to obtain details in picture. Some examples include of this are , , hand characteristics (scraps and cuts), bullet hole patterns, and other objects. form.
- Scratches on wood floors
- Shoe markings
- Hand characteristics (e.g. scrapes and cuts)
- Bullet hole patterns
We use a variety of software and applications to not only gather and fully comprehend what is seen in a picture, but to also determine if a photo was altered.
We are frequently asked to review and detect characteristics of an image to ensure the validity of that photograph. The above analysis is an important function to execute because it may be a deciding factor or contributor in the reconstruction stages of a case.
VIDEOMETRICS
At IRSA, we take part in Videography, more specifically, Video Forensics, a scientific assessment of a subject incident. We analyze the given footage through the latest software while ensuring we follow the best practices. We want to make sure the video is examined with the highest integrity and fullest professional knowledge.
We are given large amounts of surveillance and dash camera footage; enhancing it with forensic software in the common case of poor image quality.
Video evidence will always be a valuable tool for unveiling the truth, though there are often hidden or muffled details. Our job is to enhance, insert visual aids (e.g. tracking boxes), perform frame-by-frame analyses and uncover information invisible to the untrained eye.
Similar to Photometrics, we can duplicate the lighting and contrast of the site at the time of the accident. Furthermore, we are able to
- Track objects/motion
- Create Higher Clarity/Resolution
- Produce finer visual detail
- Handle various raw video formats
- Establish spatial relationships
- Perform 3D Analysis
- Read time codes
- Accurately recreate details/colors of the scene
Our goal is to inspect, understand, and accurately communicate what was analyzed and discovered through the above processes. We have the ability to take this information and use it as a support for our other scientific findings.
