Hi,
Mat landmarks
: I just landmarked them by hand on an image and copied the coordinates, the goal is just to provide a simple example. It's the 2D landmarks on a face image.
Will this time dedicated to other image file of the test need to change it?
I'm sorry, I unfortunately do not understand your question!

Hi, Patrik
Thank you for your reply. your “Mat landmarks” coordinate is around 500
I have read a .pts file about ibug ,I get landmark coordinate e.g,187.844833,186.082748,96.007217,146.086288,231.066940,280.085144,133.310715,186.358597,237.496811,186.515488,342.358246,366.692749,264.464661,273.385010,282.680420,282.681854,401.905457,404.223694,404.245697,425.630554
But your code output:pitch=-510.209, yaw=1159.74, roll=463.321

Hi,
You have to keep in mind my example is a toy-example to show how to use the library and how to make it work for your own applications. I think what is most likely happening could be the following: If you look at these lines I just generate 500 random training samples. Probably the values of your landmark coordinates do not match the distribution of these training samples, that's why you get an unexpected result. You should think about what training data to use, and also you would probably want some kind of normalisation of the translation, the translation is actually probably the main reason why your example doesn't work.

Hi, Patrik
your reply:Probably the values of your landmark coordinates do not match the distribution of these training samples.
I also think,but I don't know how to match the distribution of these training samples? how to transform?
I hope you can send me about code。
thanks!

You should read the original paper, you can find it on arXiv. Particularly the parts about the pose estimation, since that's what you want to do. It really depends on your application, but I think the first thing I'd think about is how to handle translation. The paper should give you a good idea about that. Also in my example I just generate 500 random samples, you can of course generate more, or even better, learn from a database like AFLW or something like that, they have over 25'000 faces with annotated pose labels.
