In the paper, the new approach to identification and verification of people based on the palm vein pattern will be presented. To create the feature vector, palm vein shape geometric arrangement will be applied. For detailed features will be considered similarly to minutiae which was applied in finger lines analysis in vein endings and bifurcation. The methods of vein location on the inner hand, methods...
This work presents the methods of improvement of biometric images contrast, and it corresponds to one of the main parts of the biometric system that verify identities based on distribution of the blood vessels in a hand. The acquisition of the palm blood vessel pattern causes noises that can prevent the right verification. To solve this problem, we investigate four different methods of contrast enhancement,...
The work covers issues related to the design of biometric systems based on the hand vascular pattern. The study includes analysis of various stages of biometric systems design ranging from acquisition, feature extraction and biometric pattern creation for verification methods. The extraction methods based on two-dimensional density function and the extraction of the characteristic points - minutiae...
This paper describes implementations of the Hough Circle Transform and the Radon Line Transform. The presented transforms were used to build a system for identifying road signs from selected images and recordings. This can be very important and especially useful for monitoring and prevention in driver assistance systems. The design of our system assumed that the objects should be found automatically...
Praca dotyczy wykorzystania cech biometrycznych, wynikających z wyglądu twarzy, do celów weryfikacyjnych. Opisano w niej różne metody doboru i analizy cech podczas rozpoznawania twarzy. Zamieszczony opis zawiera przede wszystkim możliwość analizy, a w późniejszych etapach – weryfikacji tożsamości na podstawie cech asymetrycznych twarzy. Zaproponowano nową metodę weryfikacji na podstawie wyznaczonych...
