This repository contains Python framework for palmprint recognition using Convolutional Neural Networks, the main functionality is:

  • learning filters from palmprint images
  • learning embedding of the palmprint image into low dimensional feature vector
  • learning binary classifier comparing couples of images
  • dataset processing and result evaluation

Dependencies

Lasagne - CNN implementation (layers, objectives, ...)

Theano - CNN implementation (symbolic expressions, ...)

Seaborn - visualization

SciPy - image processing and visualization

Bob - biometrics (evaluation)

Sample models

IITD model - trianed on the 1st half of the IITD dataset - leaves 2nd half for testing

Casia model - trained on the 1st half of the Casia dataset - leaves the 2nd half for testing

The two pre-trained models can be downloaded from here:

Used datasets

Casia touchless palmprint database (2D) (Info)

IITD touchless palmprint database (2D) (Info)
