An implementation of various colormaps for OpenCV2 C++ in order to enhance visualizations. Feel free to fork and add your own colormaps.
Sample code that doesn't belong to a specific project.
- Skin Color detection
- PCA
- TanTriggs Preprocessing

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.

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.

Fisherfaces implementation with the OpenCV2 C++ API. Here's my answer on stackoverflow.com and here's my blog post on Fisherfaces in OpenCV. If you want some insights how this stuff works, you can read through my post and experiments with Fisherfaces and Eigenfaces.
