Iris recognition using multiscale morphologic features ...
For feature extraction purpose we develop a novel feature extraction algorithm using multiscale morphology. Here multiscale top-hat transformation is used to extract structural/textural features. First, the multiscale morphologic operator is applied on normalized iris image using a line structuring element with different orientations and scales....

A multiscale directional operator and morphological tools ...
2. Mathematical morphology. Our approach for reconnecting fingerprint ridges is based mainly on some mathematical morphology transformations , , , briefly discussed in this section, and on the multiscale directional operator introduced in Section 3. 2.1. Erosion and dilation
