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. | 08-11-2011 |
20110221933 | BACKLIGHT DETECTION DEVICE AND BACKLIGHT DETECTION METHOD - Disclosed are a backlight detection device and a backlight detection method. The device comprises a pixel value acquiring unit used to acquire a pixel value of each of pixels in an image; a focal position determination unit used to determine a focal position in the image; a subject area determination unit used to determine, based on the pixel values of the pixels in the image, a subject area starting from the focal position by using an area growth processing so as to divide the image into the subject area and a background area; a brightness difference calculation unit used to calculate a brightness difference between the subject area and the background area; and a backlight determination unit used to determine, based on the brightness difference, whether the image is in the backlight state so that the image in the backlight state can be detected. | 09-15-2011 |
20120114250 | METHOD AND SYSTEM FOR DETECTING MULTI-VIEW HUMAN FACE - 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. | 05-10-2012 |
