FERA 2014 chairs´ welcome

It is our great pleasure to welcome you to the 2^d Facial Expression Recognition and Analysis challenge and workshop (FERA 2015), held in conjunction with the 11^th 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.
