Facial micro-expressions recognition using high speed camera and 3D-Gradient descriptor

Abstract

Facial micro-expressions were proven to be an important behaviour source for hostile intent and danger demeanour detection [1]. In this paper, we present a novel approach for facial micro-expressions recognition in video sequences. First, 200 frame per second (fps) high speed camera is used to capture the face. Second, the face is divided to specific regions, then the motion in each region is recognized based on 3D-Gradients orientation histogram descriptor. For testing this approach, we create a new dataset of facial micro-expressions, that was manually tagged as a ground truth, using a high speed camera. In this work, we present recognition results of 13 different micro-expressions.
