    摘要： A system and method for real-time multi-view (i.e. not just frontal view) face detection. The system and method uses a sequence of detectors of increasing complexity and face/non-face discriminating thresholds to quickly discard non-faces at the earliest stage possible, thus saving much computation compared to prior art systems. The detector-pyramid architecture for multi-view face detection uses a coarse-to-fine and simple-to-complex scheme. This architecture solves the problem of lengthy processing that precludes real-time face detection effectively and efficiently by discarding most of non-face sub-windows using the simplest possible features at the earliest possible stage. This leads to the first real-time multi-view face detection system which has the accuracy almost as good as the state-of-the-art system yet 270 times faster, allowing real-time performance.

    摘要翻译： 用于实时多视图（即，不仅仅是前视图）面部检测的系统和方法。 该系统和方法使用增加复杂性和面部/非脸部鉴别阈值的检测器序列来尽可能快地丢弃非面部，从而与现有技术系统相比节省了大量的计算。 用于多视角人脸检测的检测器 - 金字塔架构使用粗略到精细和简单到复杂的方案。 该架构解决了长时间处理的问题，通过在最早阶段使用最简单的可能特征来废弃大多数非面子子窗口，从而有效且高效地排除了实时面部检测。 这导致了第一个实时多视角人脸检测系统，其精度几乎与最先进的系统一样好，但是快了270倍，从而允许实时性能。

    摘要： A novel statistical learning procedure that can be applied to many machine-learning applications is presented. Although this boosting learning procedure is described with respect to its applicability to face detection, it can be applied to speech recognition, text classification, image retrieval, document routing, online learning and medical diagnosis classification problems.
