---------------------------------------
This folder contains the supplemental material for the paper:
Jianjiang Feng, Jie Zhou, and Anil K. Jain, "Orientation Field Estimation for Latent Fingerprint Enhancement", submitted to IEEE TPAMI, 2012.
---------------------------------------
ReferenceList.txt - Filename list of 50 reference fingerprints in NIST SD4 used for dictionary construction.
CheckOrientationField.m - Check the orientation fields of three algorithms and manual marking.
DrawDir.m - Internal function called by CheckOrientationField.m.
Benchmark.m - Measure the accuracy of orientation field estimation algorithms.
---------------------------------------
Four subfolders (OF_Proposed, OF_FOMFE, OF_STFT, OF_manual) contains the orientation fields of 258 latents in NIST SD27 obtained by three algorithms and manual marking.
The orientation field, which is defined on 16x16 blocks, can be read using 'load' function of MATLAB. The range of orientation element is (-90, 90] degrees. Value of 91 means invalid orientation elements.
