Impact of Drug Abuse on Face Recognition Systems

Drug abuse leads to high degree of the change in the facial structure of a person due to multiple factors which include loss of fat in face, change of facial structure due to changes in facial muscles and change of skin texture due to appearance of acnes. The combination of such effects lead to completely deformed face which presents a complex challenge to face based authentication systems. To study the impact of the drug-abuse on face recognition systems, in this work, we create a new face database collected before and after the drug-abuse. The newly collected database which is referred as Drug Abuse Database (DAD) consists of images obtained from 101 subjects. Further, the collected database is analysed using various state-of-art face recognition algorithms along with a widely used commercial-off-the-shelf (COTS) system. The obtained performance of GMR = 12.90% at FMR = 0.01% indicates the challenge presented by such face images and underlines the importance of newer algorithms to handle such challenge.
