Viola/Jones (2001) Object Detection Framework
The algorithm has four stages:
• Haar Feature Selection
• Creating an Integral Image
• Adaboost Training
• Cascading Classifiers
Haar Features
- The eye region is darker than the upper-
cheeks.
- The nose bridge region is brighter than the
eyes
Supported by OpenCV !
