| Popis: | Audiovisual sequences in the BANCA database are degraded in quality so that they resemble audiovisual sequences recorded using the in-built sensors of a handheld PDA device. The quality of the new database is therefore reduced on a number of levels, but the recordings remain equivalent. This process is applicable for any given high quality audiovisual database and set of lower quality sensors. More specifically, this work has been carried out in the context of the SecurePhone project, the aim of which is to develop a multimodal biometric identity verification system embedded on a PDA device. Initial results show that this adaptation process produces adequate audiovisual sequences for a given PDA device, removing the need to record a training database for each new PDA device. |
