摘要：Latent fingermarks are ridge skin deposits generally left unintentionally on surfaces such as those found at crime scenes. These marks often represent only part of the whole fingermark and their quality are generally low due to damage caused by overlaps, slips, rubbing, excess pressure, contaminants, surface and environmental conditions, among others. For this reason, fingermark experts usually must edit latent marks images in order to enhance their quality and, consequently, obtain higher minutiae quantity to use in the comparison process. This work is focused on the image composition from multiple fingermark photographs. Two practical cases where the use of multiple images can be useful are presented. The first one consists in an experiment performed to demonstrate the partial and non-uniform development of fingermarks on brass surfaces using gun blue solutions. The second is related to fingermarks recovered from a real crime scene, developed side-by-side in the same surface, thought to be originated from the same source. In both cases it is possible to take advantage of the best ridge details present in different regions of each photograph to create a richest minutiae fingermark more suitable for comparison.
