Can any body help please to understand the minutiae based algorithm matching.I'm having some difficulties understanding the alignement based matching algorithm propsed in:Lin Hong. "Automatic Personal Identification Using Fingerprints", Ph.D. Thesis, 1998. Thank you.
Hi Brad,
Ihave to classify the fingerprint image and for that I need to find the singular points(Core and Delta).There is many methods to Detect the singularities in a fingerprint image the one I use is the following:
1)Compute the orinetation Fields Estimation(Directional Image).
2)Calculate...
Orientation field is the local orientation of the ridges in the fingerprint.there is a lot of methods to calucalte the orientation field but I used the least square orientation estimation algorithm.The algorithm is described in A. Jain, L. Hong, and R. Bolle, “On-Line Fingerprint...
HI leekk, for the poincaré index algorithm that you posted,you used the orientation field estimation which was an NxN image.But with the algorithm that I used (the least square algo) the result is not an NxN image. So could you please Help Me.I'm realy confused.Can anybody help me.
Hello everybody, I'm doing a projec about fingerprints recognition, and to classify the fingerprints images into Five classes I need to calculate the ORIENTATION FIELD. I used for that the least square orientation estimation algorithm. The result must be an image NxN.But with the method I used...
