HOW CAN AL­MOST ANY PHOTO RE­VEAL YOUR IDEN­TITY?

Un­til re­cently, pho­tos taken in pro­file (1) were vir­tu­ally use­less for fa­cial-recog­ni­tion pur­poses. To­day, Foren­sicagps soft­ware can trans­late these pho­tos into front-fac­ing im­ages. The pro­gram codes up to 40 ori­en­ta­tion points (2) that can be man­u­ally cor­rected where nec­es­sary. Us­ing these points the sys­tem con­structs a wire-frame model (3), which ren­ders the outer con­tours. The pro­gram then lays the pho­tographed face onto this frame (4). Thanks to fa­cial sym­me­try, the other half of the face can be mir­rored (5)— and the re­sult­ing 3-D model can be ro­tated so the face may be viewed from var­i­ous an­gles. The frontal view is es­pe­cially use­ful for com­par­i­son with wanted pho­tos or Face­book pho­tos. The soft­ware can place po­ten­tial hits on the model (6) to com­pare fa­cial fea­tures.
