Narrow Results

The concept of capturing a palmprint using a scanner is not new, but the current palmprint capture devices based on a scanner have the limitations of low speed and large weight. A new palmprint capture device based on a scanner has been developed, which can overcome these limitations. A scanner based palmprint verification system (PVS) has also been designed using the proposed palmprint capture device. A commercially available mobile internet device (MID) was used to execute the whole program and to store the collected palmprint images. A small palmprint database was built using the developed palmprint capture device and the experimental results on this palmprint database showed that the designed system achieved an acceptable level of performance. The proposed PVS has a stable performance, small size and low price, and can meet the practical needs of civil palmprint applications.

This paper presents a fast palmprint verification system based on fractal coding. In the stage of registration, a sub-image from user's training palmprints is intentionally extracted and stored as his or her template. In the stage of verification, the step of region of interest extraction is not needed, the sample image is directly matched with the template based on fractal coding, which can reduce the whole response time. Whether the sample image and the template are from the same person or not is decided by their matching scores. Experimental evaluation results on two databases clearly demonstrate the effectiveness of the proposed approach.
