Quick and Easy Head Pose Estimation with OpenCV [w/ code]

[ivionday]

If you consider the narrow range of your samples - having pitch yaw and roll pretty much constrained within 10 degrees - your error is pretty big.

[kosomonova]

can you explain the 3x3 rotation matrix?

e.g. how do 9 discrete values translate into 3 values- pitch roll and yaw?

Looks like the results are just ok, especially in yaw (looking left to right) estimation
