Micro-expressions can occur when a person attempts to conceal and suppress his true feelings and emotions, both deliberately or unconsciously.In recent years, facial micro-expression analysis has received tremendous attention in the field of psychology, media and computer vision. However, due to its subtlety and brief duration, development of automated micro-expression detection and recognition system are still great challenges in the field of computer vision. In this paper, we present a novel hybrid facial region extraction framework that combines heuristic and automatic approaches to better recognize spontaneous micro-expressions. Salient facial regions are statistically determined based on the occurrence frequency of facial action units instead of holistic utilization of the entire facial area. The regions were automatically selected according to the facial landmark coordinates. We tested on two recent
