Finally, this is in a good state for merge. The vanilla-biometrics pipeline was not ready to handle VideoLikeContainer. Follow below a set of updates I've done along with the stack.

• bob.bio.base Updated the enrolment and scoring function to handle a list of features coming from video sequences, which are naturally 3d sequences.
• bob.bio.base Updated the score_reduction_operation to properlly reduce the scores that comes from a video sequence
• bob.bio.face. Some features extractors were returning zXnXd numpy arrays once memory_demanding==True. This is a bug. Feature extractors (the ones where features are numpy arrays) should always return nXd no matter what is set in memory_demanding
• bob.bio.video. Created a wrapper that given a scikit-learn pipeline, wraps all it's estimators with VideoWrapper. Also, the entry-point video-wrapper was created. In this way, we can automatically use all our face recognition baselines in video databases.
• bob.bio.video. Ported the YouTube faces dataset to the new Database API. In this way, bob.db.youtube can rest in peace.
• bob.bio.video. Documented the bob.bio.video package containing instructions on how to use the video support and a FAQ section describing how to customize the frame selector.

I'm running some experiments of fold0 with some of our baselines and seems that the plots are sensible. eval_plots.pdf

This depends on:

• bob.bio.face!133 (merged)
• bob.bio.base!264 (merged)

Perfect, great work! Thanks a lot!

Unfortunately, the build failed. Is it possible that the required packages of bob.bio.base and bob.bio.face are not available yet? Or are there other issues?

Hey @mguenther,

@amohammadi is working on the conda setup this week, so we currently don't have beta packages to be installed. You would need to buildout them
