• Rastr

(noun): Criminal evidence processing and restoration software.

What is RASTR?

RASTR is a software that digitizes the fingerprints, palm prints, and footprints collected from crime scenes. RASTR is able to process and  restore prints that are deformed or became indistinct due to attempts of spoliation or time.

How Does RASTR Work?

Spoiled and deformed crime scene prints are transferred to RASTR to be processed. RASTR assesses the prints and determines areas where quality could be improved. Then, depending on the investigators’ needs, interventions such as accentuation, quality improvement, and completion could be performed on pieces of evidence. Thanks to accentuation, pieces of evidence such as handwritten notes or letters become more legible and suitable for graphological analysis. In pieces such as finger and foot prints, the accentuation process reveals the details of prints and enables suspect identification by using the said prints and a software like PAPILON APFIS. Completion allows crime scene experts to complete a deformed print depending on their professional knowledge and experience. RASTR preserves the original version of the evidence and resaves the evidence after each change and application. That way, all the changes to which the evidence is subjected are recorded for later reference. RASTR has two datasets; the viewing dataset that allows the experts to see and compare all versions of a piece, and the graphics dataset where the analysis and statistical information about pieces of evidence are kept.

Why RASTR?

1- Rescale

RASTR allows  small pieces evidence can be magnified, or can be scaled down to view the evidence in its entirety..

2- Rich Set of Applications

RASTR has a rich set of effects and applications to restore the evidence. With RASTR, brightness, density, and color system can be modified. This feature allows the digital representation of match the physical evidence.

Where to Use RASTR?

RASTR is used in criminal cases to improve evidence quality and prepare pieces of evidence for effective analysis. 

When Will You Need RASTR?

You will need RASTR when you want to solve cold cases, when you want to render attempts of spoliation and evidence manipulation void by improving the quality of deformed pieces of evidence.

Who Can Use RASTR?

Using RASTR requires expertise in crime scene investigation and evidence analysis. Thus, the ideal user of RASTR are crime scene and evidence analysis experts.
