February - A review by Gary Wells and Lisa Hasels of Iowa State University published in Current Directions in Psychological Science has found that recent technological advances in facial composite systems have failed to improve identification and apprehension of criminal suspects. The era of an artist's skilful pencil sketches has been replaced by computer software offering witnesses a huge range of different facial features. The review highlights poor results from such facial composite systems. In one study, only 2. In separate research, participants were unable to discriminate composites of their classmates from those of students at different schools. The report suggests that these poor results do not reflect software deficiencies as such but more a discrepancy between how we remember faces and how composites are produced.
Please take this quick survey to tell us about what happens after you publish a paper. Artificial Intelligence Review. In criminal investigation, a facial composite refers to a portrait of a sought unknown individual created by a forensic technician based on the memory of the eye-witness. Although different software solutions were proposed, the main principles of the construction process remained the same since manual sketching. The process still relied on the detailed description of offenders and their individual features with the purpose of merging the individual features together in order to create a final portrait. This paper compares the techniques used for the construction of composites, summarises psychologically—criminological research on human perception, processing and recall of unknown faces, as well as a review of the new generation systems which automatically generate facial images in terms of facial representation and the applied optimisation method GA.
The mention of facial composites often conjures up images of a sinister criminal, skillfully depicted by a sketch artist using pencil and paper. In reality, the vast majority of law enforcement agencies use mechanized methods, usually computer software, when creating facial composite. By having a vast repertoire of eyes, ears, hair and so on at their disposal, witnesses have the ability to create an image that ideally encompasses all of the features of the perpetrator. So have these technological advances improved our ability to identify and apprehend criminals?
