====================== Implementation Details ====================== For more information about face recognition algorithms, please check :ref:`bob.bio.face ` which contains several different algorithms to perform photometric enhancement of facial images are implemented. In this package several face feature extractors and their respective recommended preprocessors are available. Feature extractors ~~~~~~~~~~~~~~~~~~ The following models are available: * :any:`The VGG face model ` ( ``'vgg_features'``) * :any:`The LightCNN face model ` (``'lightcnn'``) Further models can be wrapped easily using the tools available in :ref:`bob.ip.caffe_extractor` and this package.
