Figerprint Segmentation

In a fingerprint recognition system only fingerprint region of scanned image should be taken into account. Hence, it is necessary the ROI to be segmented from background. Different methods have been proposed for fingerprint segmentation. In this paper, some of the most important methods are introduced and implemented. Then one of them is modified and based on it, an adaptive and supervised method is proposed. Finally, all of implemented methods and the proposed method are evaluated and compared to each other. The DB2_A of FVC2004 is selected as a standard database, to implement each method. The experimental results demonstrate the effectiveness of the proposed method, concerning the extraction of ROI, especially in low quality images.
