Paper Abstract

Current police tools of identification are flawed. The lineup suffers from being too small and no adequate solution to a criterion of similar foils. The mugshot search suffers from too many photos and inadequate procedures for choosing an appropriate subset. The composite, from inappropriate methods of selecting facial features. Our new mugshot search provides solutions to some of the problems. Witnesses choose photos similar to the offender, and the computer, using a similarity network, helps witnesses reach the offender faster. Replacing mugshots with foils, we can use the same technique as a lineup, that is significantly enlarged and leaves the choice of similar foils to the witnesses. When the mugshot search fails, a composite can be composed as a superimposition of the photos most similar to the offender. Several algorithms were tested for implementing the similarity network. They involve both the establishment of a meaningful distance criterion within 'face space' and the usage of efficient search strategies. Here, we discuss their benefits and drawbacks. A system comprising the full local album of the Haifa district (more than 10,000 photos) is presently being subjected to a field test by the Isreali police. We briefly describe the system and its user interface.
