Abstract:
Objective Digital analysis of human bitemarks by blind method was assessed for its accura-cy. Method Digital analysis was used in double-blind method for identification of human bitemarks with control samples from 8 suspects. Photoshop 5.5 generates an overlay from bitemarks scanned and various coefficients were submitted for analysis by AutoCAD R14 engineering software to compare bitemarks with denture of suspects. Results Digital analysis shows that bitemarks tally with cast of denture from "suspects" in every coefficient. Conclusion Digital analysis is feasible for identification of experimental bitemarks and promises sound prospects in future forensic practice.
