Anil K Jain, Lin Hong, Rudolf Maarten Bolle, Sharathchandra Umapathirao Pankanti: System and method for determining block direction in fingerprint images. International Business Machines Corporation, Louis J Percello, Perman & Green, September 11, 2001: US06289112 (327 worldwide citation)

A reliable estimate of image pixel (fingerprint ridge) orientations, and block orientations for a given block is determined by finding an optimal block size in an area of an image, e.g., a fingerprint image. An initial block size is chosen. Then a block direction is determined, e.g., by analyzing in ...

Anil K Jain, Lin Hong, Rudolf Maarten Bolle, Sharathchandra Umapathirao Pankanti: System and method for matching (fingerprint) images an aligned string-based representation. International Business Machines Corporation, Louis J Percello, Perman & Green, February 6, 2001: US06185318 (106 worldwide citation)

The invention is a system and method for matching a two dimensional pattern of lines, e.g. a fingerprint, by creating a one dimensional representation of one or more points (e.g., minutiae) on the lines in the patterns to be matched. The one dimensional representations are created by finding a corre ...
