An multi-scale iris recognition algorithm based on radon transform
Sidan Du · 2007
In order to solve some general problems in existing iris recognition algorithms such as sensitivity to noise and long calculation time for extracting 2-D feature etc,a new algorithm for iris identification of human eyes based on radon transform and multi-scale analysis was presented.First, radon transform was used to project the its texture to 1-D space,then multiscale analysis was implemented to extract its feature.Energy values at different scales could effectively reflect the different energy distributions of iris texture and thus were recorded as a feature vector.At last,the feature vector was compared with model features through a dissimilarity function in order to classify different iris samples.Experiment results show that the algorithm is efficient while it is translation,rotation and scaling invariant as well.
