Query: Advanced local motion patterns for macro and micro facial expression
  recognition   In this paper, we develop a new method that recognizes facial expressions, on
the basis of an innovative local motion patterns feature, with three main
contributions. The first one is the analysis of the face skin temporal
elasticity and face deformations during expression. The second one is a unified
approach for both macro and micro expression recognition. And, the third one is
the step forward towards in-the-wild expression recognition, dealing with
challenges such as various intensity and various expression activation
patterns, illumination variation and small head pose variations. Our method
outperforms state-of-the-art methods for micro expression recognition and
positions itself among top-rank state-of-the-art methods for macro expression
recognition.
