| 摘 要： | 旋转45°矩形窗口的积分图像用于计算旋转Harr型特征,可实现快速人脸检测.通过改进这种积分图像的算法,不仅提高了其计算速度,而且使获得图像直立矩形窗口和旋转45°矩形窗口的积分图像只需遍历原图像一次.实验证明算法改进是有效的.还提出了利用这种积分图像检测平面内旋转人脸的另一种方案,拓展了其应用.

| Abstract: | Integral image of 45 degree rotated rectangle windows is used to compute the rotated Harr-like features for rapid face detection.Through the improvement of the integral image algorithm,the computing speed is accelerated,and the integral images of upright windows and 45 degree rotated windows are gained through the search of the origin image only once.Experiments indicate that the improved algorithm is efficient.Another scheme for detecting rotated human faces with such integral image is proposed,which shows... |
