             abstract = "In this article we propose a technique to detect the reference 
                         point of a fingerprint based on the main supposition that the 
                         crests belonging to the superior area of reference point usually 
                         have a orientation quantized of 0°. To take advantage of this fact 
                         it is accomplished an analysis of the orientation image 
                         considering their multiple levels of representation in relation to 
                         their values of quantization. This is a new approach that allows 
                         the use the morphologic characteristics of the quantized 
                         orientation image for each value of quantization. The technique 
                         presents some important characteristics: adaptability according to 
                         the quality of the image and the possibility of detecting the 
                         reference point of the fingerprints A and TA with acceptable error 
                         rate for these type of fingerprint. The technique is tested in the 
                         whole database of DB4 of NIST getting an estimation error of the 
                         reference point of 8.32% for a total of 4,000 images.",
