Cascading is a particular case of ensemble learning based on the concatenation of several classifiers, using all information collected from the output from a given classifier as additional information for the next classifier in the cascade. Unlike voting or stacking ensembles, which are multiexpert systems, cascading is a multistage one.
The first cascading classifier is the face detector of Viola and Jones (2001). The requirement was that the classifier be fast in order to be implemented on low CPU systems, such as cameras and phones.
Algorithm properties
scaling and rotations
It can be seen from this description that the classifier will not accept faces that are upside down (the eyebrows are not in a correct position) or the side of the face (the nose is no longer in the center, and shadows on the side of the nose might be missing). Separate cascade classifiers have to be trained for every rotation that is not in the image plane (side of face) and will have to be retrained or run on rotated features for every rotation that is in the image plane (face upside down or tilted to the side). Scaling is not a problem, since the features can be scaled (centerpixel, leftpixels and rightpixels have a dimension only relative to the rectangle examined). In recent cascades, pixel value from some part of a rectangle compared to another have been replaced with Haar wavelets.
