Title: METHOD OF MATCHING A SKETCH IMAGE TO A FACE IMAGE
Abstract:
The performance of automated facial forensic sketch matching is improved by learning from examples of facial forgetting over time. Forensic facial sketch recognition is a key capability for law enforcement, but remains an unsolved problem. It is extremely challenging because there are three distinct contributors to the domain gap between forensic sketches and photos: The well-studied sketch-photo modality gap, and the less studied gaps due to (i) the forgetting process of the eye-witness and (ii) their inability to elucidate their memory. A database of forensic sketches created at different time-delaysis used train a model to reverse the forgetting process. Surprisingly, this enables a model to systematically "un-forget" facial details. This model is applied to dramatically improve forensic sketch recognition in practice.
