| Abstract: | It is important to estimate ridge distance of fingerprint images accurately and reliably for automatic fingerprint identification. Though some researchers have already studied on this problem, up till now, no satisfying solution has been found. It makes a deep research on this problem and implements the estimation of ridge distance of fingerprint images based on spectrum analysis with big window. Experimental results on some typical fingerprint images from FVC2000 and FVC2002 indicate that our method is effective and robust. |
