The understanding of an image deals with the consideration of the most banal information conveyed by each pattern. A crucial anchor for facial expression analysis is to consider not only permanent features but transient ones too. In this work we are interested by all the outcomes of transient features in the analysis of facial expressions. Three processes based on transient features are propose...

Human face analysis has attracted a large number of researchers from various fields, such as computer vision, image processing, neurophysiology or psychology. One of the particular aspects of human face analysis is encompassed by facial expression recognition task. A novel method based on phase congruency for extracting the facial features used in the facial expression classification procedure ...

Automatic facial action unit (AU) detection from video is a long-standing problem in facial expression analysis. Existing work typically poses AU detection as a classification problem between frames or segments of positive and negative examples, and emphasizes the use of different features or classifiers. In this paper, we propose a novel AU event detection method, Cascade of Tasks (CoT), which...
