Vinayak Dagadu Shinde, Vijay Mahadeo Mane · International Journal of Computer Applications · 2012
An approach for feature extraction using wavelet transforms using its property of multilevel decomposition in pattern recognition application is proposed.The multilevel decomposition property of discrete wavelet transform provides texture information of an image at different resolutions.Iris recognition system using multilevel wavelet transform is explained.The technique developed here is implemented using three and four level decomposition of Discrete Wavelet Transform.Four level decomposition gives better results at increased threshold value.Reduced feature vector size improves the speed.
