Fingerprint Image-Quality Estimation and its Application to Multialgorithm Verification
Fingerprint Image-Quality Estimation and its Application to Multialgorithm Verification
Signal-quality awareness has been found to increase recognition rates and to support decisions in multisensor environments significantly. Nevertheless, automatic quality assessment is still an open issue. Here, we study the orientation tensor of fingerprint images to quantify signal impairments, such as noise, lack of structure, blur, with the help of …
