Touchless Fingerprint Sensors
Our strategy is to rapidly preprocess imagery
acquired from sensors, which will substantially reduce the
amount of data transmitted to the final processing unit, thereby
dramatically reducing energy consumption. Only vetted salient
information and features need to be forwarded on to the final
processing unit. Specifically, we are developing a CMOS based
sensor system that will capture the fingerprint image of each
finger using optical illumination with blue, green and red
wavelengths to enhance contrast ratios. In addition, the system
will capture three views of the finger (one bottom and two
side views) that will allow us to convert the acquired fingerprint
into “flat” prints for direct comparison to prints
obtained using traditional methods. |
