At present, the three datasets have the following characteristics:
- DS3-Mobile dataset (mobile device-based, indoor/outdoor environment, uncontrolled conditions)
- Modalities included: voice, face, signature and fingerprint
- Sessions: 2
- Donors: 713
- The objective of this dataset is to have a multimodal database with several modalities acquired on current mobile platforms. For audio-video recordings two different acquisition conditions are considered: indoor and outdoor, with sources of variability for each modality. For signature and fingerprint recordings only one degraded acquisition condition is considered, because controlled quality data are recorded in DS2.
- Hardware devices used for the acquisition include a PDA HP iPAQ hx2790 (for fingerprint and signature) and a Mobile PC SAMSUNG Q1 + Web Cam (for face and voice).
