Viola and Jones Object Detection Framework (C++)

This is an implementation of the [Viola and Jones Object Detection Framework][1] in C++. It has been particularly optimized for the face detection paradigm:

• Horizontal flipping face sample images in training phase.
• Rotating negative sample images in training phase.
• 4 Haar features implemented.
• Integral image for faster processing.
• Post-normalization speedup.
• Scale invariant (feature scaling).

Installation --------------

git clone https://github.com/alexdemartos/ViolaAndJones.git violaandjones
cd violaandjones/src
g++ -std=c++0x -lpng -O3 Feature.cpp WeakClassifier.cpp StrongClassifier.cpp CascadeClassifier.cpp main.cpp -o vandj `libpng-config --ldflags`
chmod +x vandj

Usage

• Run ./vandj without arguments to see the options.
• No classification models are provided for object/face detection, you must train your own.
• No images nor training samples are provided.

Example

I've used this program to train a face detection algorithm. Here are some results:
