Dear Mr Yu, Hello,sir! You libfacedetection lib is so cool, thanks for your contribution.Now I have a quertion,that is about the poter pResults. In the code the face rectangular box together with the 68 key points neighbors and yaw angle can be get from the pResults. In fact I do not understand how to get all these just by short p = ((short)(pResults + 1)) + 142 * i. Look forward for your reply! Thank you!

The data structure in pResults is as follows: int nFaceCount; short face1_x; short face1_y; short face1_width; short face1_height; short face1_neightbors; short face1_angle; short face1_point1_x; short face1_point1_y; ... short face1_point68_x; short face1_point68_y; short face2_x; short face2_y; short face2_width; short face2_height; short face2_neightbors; short face2_angle; short face2_point1_x; short face2_point1_y; ... short face2_point68_x; short face2_point68_y; ...
