Similarity, analogy, compatibility, identification: personal identification in forensic practice.

In the field of personal identification focused on images processing extracted from video surveillance systems, as in the cases presented by the authors, there are lot of critical issues and limitations, which could undermine data. Correct personal identification can be achieved by comparing the clearly visible and objectively recognizable somatophysical and physiognomic characteristics of the offender with those of the suspects. So how compatible are two subjects compared? Compatibility and identification are two very different con-cepts. It is not necessarily the case that full compatibility is equivalent to personal identification. It is not necessarily the case that the absence of morphological similarity is equivalent to identification exclusion.
