A computer-based method developed for the purpose of checking the results of identification performed with the "traditional" method of video-superprojection (developed by Helmer and Grüner) is demonstrated; it does not require any special programs in addition to those necessary for digitising the video pictures. The method is suitable for filtering out "false-positive" cases. A great advantage is that the phase of computer evaluation can be separated from the job performed in the video studio, both in time and space. The process can be reconstructed, which means it can be checked. The results can be easily documented and interpreted for lay people.
