FERA 2014 chairs' welcome

It is our great pleasure to welcome you to the 2d Facial Expression Recognition and Analysis challenge and workshop (FERA 2015), held in conjunction with the 11th IEEE International Conference on Automatic Face and Gesture Recognition (FG 2015). It's been four years since the first facial expression recognition challenge (FERA 2011), and we're excited to come back to challenge researchers worldwide to go ever further in the automatic recognition of facial expressions. This year's challenge and associated workshop pushes the boundaries of expression recognition by focusing on the estimation of FACS Facial Action Unit intensity, as well as regular frame-based occurrence detection. The challenge is set on previously unreleased data of extensive duration (over 350,000 annotated frames) of relatively naturalistic scenarios taken from the BP4D and SEMAINE databases.
