Abstract
A system comprising a polarization CMOS image sensor, at least one processor and a non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the at least one processor, cause the system to perform actions including receiving, from the polarization CMOS image sensor, polarization information and two-dimensional image information. The polarization information is processed using a machine learning model to generate an output that indicates whether the polarization information represents a valid biometric measurement of a physical feature of a subject.
