Precise Reconstruction of Damaged Parts in Fingerprint Images
Šmotláková, Lucia Mária ; Sakin, Martin (oponent) ; Kanich, Ondřej (vedoucí práce)
The aim of the bachelor's thesis is to locate the damaged areas in fingerprints and then reconstruct them using cubic Bézier curves. Structure elements and morphological operations are used to localize the damage. The break points obtained by localization are used to plot the curve. The outcome is a simple user interface that allows the user to upload a fingerprint image and observe each step of the solution of the bachelor's thesis. The achieved results were then tested and analyzed. In conclusion, it is found that the use of Bézier curves for reconstruction is not suitable for all types of damage, in particular it is not suitable for large damage in areas of high curvature.
