Extract of the conference report:
Finally, Jean-Francois Mainguet
(CEA) and Marina Pouet (IDEMIA) presented the project PYCSEL, which is aimed at
building a new flexible active thermal fingerprint sensor. The sensor must have
high resolution (500 dpi) and a large surface (76mm x 81 mm), allowing 4-finger
acquisition. The sensor must also work on rigid glass substrates, and on flexible
laminated glass with a thickness of 15ìm. During the presentation, the speakers
showed the difficulties found in the prototype construction regarding factors such
as image quality analysis, image defects and their removal (e.g. to avoid the
creation of false minutiae), or noise from the electronic board. As future work, the
project will evaluate the performance of the sensor in terms of verification accuracy,
using traditional optical sensors as baseline.
