Face detection based on multi-parts and multi-features

The local occlusion and pose variation in face detection, face can be looked on as a whole composed of several parts from up to down. First, the face is divided into a number of local regions from which various features are extracted. Each region is identified by a local classifier and is assigned a preliminary part label. A random field is established based on these labels and multiple dependencies between different parts are modeled in a CRF framework. The experiments were carried out on the CMU/MIT dataset and a higher detection rate and lower false detection rate were achieved.
