eigenfaces

Eigenfaces implementation using the OpenCV2 C++ API. There's a very basic function for loading the dataset, you probably want to make this a bit more sophisticated. The dataset is available at http://www.cl.cam.ac.uk/research/dtg/attarchive/facedatabase.html.

lbp

Implements various Local Binary Patterns with the OpenCV2 C++ API:

• Original LBP
• Circular LBP (also known as Extended LBP)
• Variance-based LBP

Basic code for spatial histograms and histogram matching with a chi-square distance is included, but it's not finished right now. There's a tiny demo application you can experiment with.
