pvl FaceDetect API has given a mechanism to set ROP angle range. I have set the ROP angle range to be 15 (I assume it takes angle in degrees) and expect it to find faces only in range of -15 to +15 degrees of rotation along y-axis. But it find all kind of faces including almost profile face. However, it returns value of "0" for faces data that's returned from detectFaceRect.
1. Is my understanding about RIP and ROP angle right -> RIP angle is for rotation along z-axis (Coming out of the screen) and ROP is rotation about y-axis (vertical direction)
2. I am using SDK version 2017.0.139
3. Platform: Ubuntu 16.04
