K Lekdioui, R Messoussi, Y Ruichek, Y Chaabi… - Signal Processing …, 2017 - Elsevier
Automatic facial expression analysis is a challenging topic in computer vision due to its
complexity and its important role in many applications such as human–computer and social
interaction. This paper presents a Facial Expression Recognition (FER) method based on an
automatic and more efficient facial decomposition into regions of interest (ROI). First, seven
ROIs, representing more precisely facial components involved in expression of emotions
(left eyebrow, right eyebrow, left eye, right eye, between eyebrows, nose and mouth), are …
