Palmprints Recognition Method Based on the Phase Consistency Combined with Log-Gabor Filter
A method of recognition of the palmprint texture,with rich information,strong stability,and low resolution collection is proposed. This method first calculates the phase congruence of every point in the palmprint image from 6 directions and sets the direction corresponding to the maximum of phase congruence of every point as the direction of log-Gabor filter,and then at that direction extracts phase information of every point of the image with log-Gabor filter,and further quantifies and codes real and imaginary parts of the phase information. Thus the palmprint phase quadrant code with 256 bytes in length is obtained. Experiments are carried on the database of 1000 images of 100 palms. The result shows that the recognition rate could reach 99.95% at given threshold. Compared with the traditional recognition algorithm based on the palmprint texture feature,this method has higher recognition rate.
