This study proposes a new fingerprint minutiae detection method with a short processing time and high accuracy. This method removes spurs, thus preserving the connectivity of the original image following the Tamura thinning. In the proposed method, the fingerprint minutiae can be correctly detected by inspecting pixels in the 8-connection of the pixel of interest, even if the line width is not equal to one. Experimental results demonstrated that the detection rates of the proposed and conventional methods are approximately the same, while the processing time of the proposed method is 1/30th of that of the conventional method.
