Integral image of 60 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 up right windows and 60 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 the extending application of integral image of 60 degree rotated rectangle windows.
