An examination of person is an initial link for identify, the problem that it handle is to confirm the picture( or image) to win whether exist person's face, if the existence then carries on the fixed position to person's face.The applied realm of an examination of person is very extensive, is one of the important steps that carries out the machine intelligence to turn.热心网友 时间:2022-06-30 12:24
The person face examination is the most important link which the person face distinguishes, its processing question is confirmed that image (or phantom) whether to have the person face, if exists carries on the localization to the person face. The person face examination's application domain is quite widespread, realizes one of machine intellectualization important steps. the AdaBoost algorithm is one kind of fast person face examination algorithm which in 1995 proposed, is the person face examination domain milestone-like progress, this algorithm acts according to the weak study the feedback, compatibly the adjustment supposition's error rate, causes, in the efficiency does not rece in the situation, the examination accuracy had the very big enhancement. the present paper used the Haar characteristic to construct the weak sorter, the use classics Adaboost method trains the strong sorter, the system narrated the Adaboost algorithm's theoretical knowledge, and experimented above the use small scale typical data has compared the procere effect, through the comparison time consumption, the memory took, the dimensionality rection proportion, recognition error rate and so on, has realized sorter's functions basically.
