19. OpenCV
OpenCV (Open Source Computer Vision Library) is
an open source library.
computer vision
machine learning
The library has more than 2500 optimized
algorithms.
24. FaceDetect
trained with particular object (positive example)
arbitrary images of the same size (negative
example)
boosted: create Strong classifier which is a
weighted sum of these weak classifiers
cascade: resultant classifier consists of several
simpler classifiers (stages)
25. Features
20*20 demo pictures
For each feature, it finds the best threshold which will
classify the faces to positive and negative
