摘要： Disclosed are an apparatus and a method for determining a multi-view specific object. The apparatus comprises an input device for inputting image data; and cascade classifiers formed of stage classifiers corresponding to a same detection angle, the stage classifiers corresponding to different features. Each cascade classifier is for calculating a degree of confidence of the image data of a specific object corresponding to the detection angle based on the aspect of the corresponding feature, and determining whether the image data belongs to the specific object based on the degree of confidence. A self-adaptive posture prediction device is disposed between two stage classifiers in each cascade classifier, and is used to determine whether the image data enters the cascade classifiers corresponding to the detection angles and located after the self-adaptive posture prediction device.

摘要： Disclosed are a system and a method for detecting a multi-view human face. The system comprises an input device configured to input image data; a hybrid classifier including a non-human-face rejection classifier configured to roughly detect non-human-face image data and plural angle tag classifiers configured to add an angle tag into the image data having a human face; and plural cascade angle classifiers. Each of the plural cascade angle classifiers corresponds to a human face angle. One of the plural cascade angle classifiers receives the image data with the angle tag output from the corresponding angle tag classifier, and further detects whether the received image data with the angle tag includes the human face.
