一种视频图像中大胡子检测的方法及系统
摘要：
本发明涉及一种视频图像中大胡子检测的方法及系统，该方法通过根据获取视频图像宽高设置该视频图像中待检测的感兴趣区域；对感兴趣区域按预设前景检测方法进行前景检测，获得前景区域；在前景区域内进行基于Haar特征的人脸检测，获得人脸区域；在所述人脸区域进行肤色检测，定位出嘴部区域；计算该嘴部区域肤色像素点占嘴部区域总像素点比例，并判断该比例是否超过设定的阈值，如超过则判定为大胡子，从而为在视频图像中有效地进行大胡子目标人物检测提供一种有效的检测手段。
摘要（英）：

The invention relates to a beard detection method and system in a video image. According to the method, a to-be-detected area of interest in a video image is set based on the width and height of the video image; according to a preset foreground detection method, foreground detection is carried out on the area of interest to obtain a foreground area; Haar-feature-based face detection is carried out in the foreground area to obtain a face area; skin color detection is carried out on the face area to localize a mouth part area; and a proportion of a skin color pixel point of the mouth part area in a total pixel point of the mouth part area is calculated and whether the proportion exceeds a set threshold value is determined; if so, a beard is determined. Therefore, an effective detection way is provided for effective detection of a target with a beard in a video image.
