In this paper, we present a strategy to implement multi-pose face detection in compressed domain. The strategy extracts firstly feature vectors from DCT domain, and then uses a boosting algorithm to build classificrs to distinguish faces and non-faces. Moreover, to get more accurate results of the face detection, we present a kernel function and a linear combination to build incrementally the strong classifiers based on the weak classifiers. Through comparing and analyzing results of some experiments on the synthetic data and the natural data, we can get more satisfied results by the strong classifiers than by the weak classifies.

Peripheral neuropathies refer to a group of conditions in which the peripheral nervous system(PNS)is damaged.These pathological state are are associated with weakness,pain,and loss of motor and sensory control.More than 100 types of peripheral neuropathies have been identified,with distinct symptoms and prognosis classified according to the type of damage to the nerves.Injury to peripheral nerves results in disabling loss of sensory and motor func- 展开更多
