Abstract: This paper presents a skin diagnosis algorithm installable in cell phones that have fingerprint identification function. The algorithm can analyse low contrast skin images captured from a fingerprint sensor based on two dimensional linear prediction analysis. The authors| devices can be smaller than conventional skin diagnosis devices having a camera, without an optical lens or a focus adjustment apparatus. Especially, it can be installed in fingerprint identification devices as a bonus application. The authors| algorithm presented in this paper has been embedded in Pantech PG-6200 mobile phone.
Keywords: fingerprint sensors; mobile phones; cell phones; PDAs; skin diagnosis; skin images; fingerprint identification.
