Applying LBP Operator to Gabor Response for Palmprint Identification
We proposed in this paper an accurate and efficient approach for palmprint identification. In this method, a Gabor wavelet is first convolved with the palmprint image to produce a response image, where LBP is then applied to code the relation among the magnitude of wavelet response at central pixel with that of its neighbors. The method is fully tested using the public PolyU palmprint database. In the experiment, 3864 test images are identified by the proposed method against the 1158 templates. While palm code achieves only about 89% accuracy, over 96% accuracy is achieved by the proposed G-LBP approach. Our approach could identify a palmprint image within 200 ms.
