金字塔式编码的BGP人脸快速检索方法
摘要：
本发明公开一种金字塔式编码的BGP人脸快速检索方法，步骤包括：S1.对数据库中各人脸图像分别进行多级BGP特征提取，并对每级BGP特征提取得到的特征向量进行编码，得到对应各级BGP的多层编码，各层编码的长度按顺序逐级缩短形成金字塔式编码结构，得到数据库图像编码；S2.对待检图像进行多级BGP特征提取，并对每级BGP特征提取得到的特征向量进行编码，得到对应各级BGP的多层编码，各层编码的长度按顺序逐级缩短形成金字塔式编码结构，得到待检图像编码；S3.将待检图像编码与数据库图像编码进行逐层比较，由比较结果识别出目标人脸。本发明具有实现方法简单、检索效率及精度高、实时性好等优点。
摘要（英）：

The invention discloses a pyramid-coded BGP face quick retrieval method, 11) carry out multi-level BGP feature extraction on each face image in that database respectively, and coding the feature vector obtain from each level of BGP feature extraction to obtain multi-level coding corresponding to each level of BGP, wherein the length of each level code is successively shortened to form a pyramidalcoding structure to obtain the database image code; and 12) carrying out multi-level BGP feature extraction on each level of BGP feature extraction to obtain a database image code; 2, extract that multi-level BGP features of the image to be chec, coding the feature vectors extracted from the BGP feature of each level to obtain the multi-level codes corresponding to the BGP of each level, and sequentially shortening the length of the codes of each level to form a pyramid-type coding structure to obtain the image to be checked; 3, compare that image coding to be chec with the image coding of thedatabase layer by layer, and recognize the target face from the comparison result. The invention has the advantages of simple realization method, high retrieval efficiency and precision, good real-time performance and the like.
