Commercial iris biometric systems exhibit good performance for near-infrared(NIR) images but poor performance for visible wavelength(VW) data.To address this problem,we propose an iris biometric syste
Based on the peak to valley ratio (PTVR) of the average magnitude difference function (AMDF), we present a novel optical signal to noise ratio (OSNR) and symbol rate (SR) estimation method for commonly used auxiliary amplitude modulations (AAMs). Moreover
