Abstract-In this work, a method for biometric recognition of ultrasound palmprint based on principal lines is proposed and experimentally evaluated.Volumetric images of a region the palm hand were acquired by moving a commercial ultrasound probe over the region of interest.The obtained 3D matrix of voxels was then post elaborated to provide 2D renderings of the palmprint at different skin depths.The recognition procedure is based on the fusion of a couple of such images.A procedure for extracting main features from the fused image was then established and a preliminary database composed by 81 sample from 27 volunteers was created.Both verification and identification experiments were performed to evaluate system performances.Results have shown the effectiveness of the fusion procedure.Further possible improvements of the method are finally highlighted and discussed.
