Iterative procedures application for image scaling

Forensic examination often involves studying various kinds of images obtained from various sources. One of the tasks assigned to an expert is to enhance image quality to obtain visually distinguishable forensically significant details, such as registration plate number or appearance details of a vehicle or a person. In the article an expert assessment of the obstacle influence on recognizing of a registration plate number is presented and the limitations for initial image quality are outlined. Furthermore, a modified image recovery algorithm is introduced for reconstructing fragments of small images, which allows to obtain additional forensically significant data.
