    • Contributions to unconstrained palmprint recognition on smartphones 

      Ungureanu, Adrian-Stefan (NUI Galway, 2019-11-27)
      This thesis investigates the suitability of unconstrained palmprint as a biometric modality for handheld devices equipped with a camera, such as smartphones. A detailed literature survey is provided, covering existing ...

    • Deep learning for hand segmentation in complex backgrounds 

      Ungureanu, Adrian-Stefan; Bazrafkan, Shabab; Corcoran, Peter (Institute of Electrical and Electronics Engineers, 2018-01-02)
      This paper presents a Deep Learning segmentation approach for hand segmentation in gray level images with cluttered backgrounds where standard techniques cannot be used. Two networks were trained with a database of hand ...

    • Unconstrained palmprint as a smartphone biometric 

      Ungureanu, Adrian-Stefan; Thavalengal, Shejin; Cognard, Timothée E.; Costache, Claudia; Corcoran, Peter (IEEE, 2017-11-13)
      In this work the use of palmprints as an alternative biometric for smartphones is investigated and its feasibility is evaluated across multiple devices using unconstrained acquisition. A novel multi-device database that ...
