47 FILE: BOZORTH3.C

49 MODIFICATIONS: Michael D. Garris (NIST)
50 Stan Janet (NIST)
51 DATE: 09/21/2004

53 Contains the "core" routines responsible for supporting the
54 Bozorth3 fingerprint matching algorithm.

56 ***********************************************************************
57
58 ROUTINES:
59 #cat: bz_comp - takes a set of minutiae (probe or gallery) and
60 #cat: compares/measures each minutia's {x,y,t} with every
61 #cat: other minutia's {x,y,t} in the set creating a table
62 #cat: of pairwise comparison entries
63 #cat: bz_find - trims sorted table of pairwise minutia comparisons to
64 #cat: a max distance of 75^2
65 #cat: bz_match - takes the two pairwise minutia comparison tables (a probe
66 #cat: table and a gallery table) and compiles a list of
67 #cat: all relatively "compatible" entries between the two
68 #cat: tables generating a match table
69 #cat: bz_match_score - takes a match table and traverses it looking for
70 #cat: a sufficiently long path (or a cluster of compatible paths)
71 #cat: of "linked" match table entries
72 #cat: the accumulation of which results in a match "score"
73 #cat: bz_sift - main routine handling the path linking and match table
74 #cat: traversal
75 #cat: bz_final_loop - (declared static) a final postprocess after
76 #cat: the main match table traversal which looks to combine
77 #cat: clusters of compatible paths
