Large scale biometrics projects rely on capturing images/signal from multiple sensors. For example, in India’s Aadhaar project, multiple fingerprint sensors of different make and model are used for data collection. Similarly, in law enforcement applications, different agencies use different fingerprint sensors. These scenarios cause two potential problems: (i) sensor inter-operability and (ii) ...

DMT is a software demonstration tool, running on workstations, that can be used to demonstrate other software tools. The paper describes the reasons for developing DMT and the implementation of DMT. DMT simulates a video recorder/player system and provides recording, winding (forward/backward) and replaying functions. During recording, DMT records the target tool window image changes and the in...

We demonstrate 100-nm-resolution holographic aerial image monitoring based on lensless Fourier-transform holography at extreme-UV (EUV) wavelengths, using synchrotron-based illumination. This method can be used to monitor the coherent imaging performance of EUV lithographic optical systems. The system has been implemented in the EUV phase-shifting point-diffraction interferometer recently devel...

The health care field is focusing considerable attention on dietary control, which requires that individuals record what they eat. We have developed a novel smartphone application called FoodLog, a multimedia food recording tool that allows users to take photos of their meals and to produce textual food records. Unlike conventional smartphone-based food recording tools, FoodLog allows users to ...
