ImgOpinion Desktop Application that Solve the Criminalistic Tasks

Abstract

The article describes the functional features of the desktop application "ImgOpinion" to extract information from a target by processing its graphic image obtained by photo means in digital form. The desktop application implements its capabilities in several scenarios due to computer vision methods, allowing for processing full-size images of 10 - 15 megapixels and outputting the processed values in *.txt and *.png formats, e.g. The gunshot traces certificate contains the necessary and relevant parameters for forensic investigators of the target object, including the parameters of the gunshot traces found on its surface. The ImgOpinion application allows the forensic expert to identify gunshot residue on a target, calculate the dimensions and the colourimetric data from digital images of the one. The application makes it possible to estimate the amount of soot on the surface of a target from a gunshot, as well as its distribution over the surface, which traditional forensic methods reveal by destroying the target.
