• Approcci possibili:
• Discrete (Ekman) vs. Dimensional (Russell)
• AU-based (Ekman) vs. holistic

Dimensional approach via Gabor wavelets

Dimensional approach via Gabor wavelets
• Lyons et al.
• Gabor and human similarity data was
analyzed usingnon-metric
multidimensional scaling (nMDS) using
theALSCAL algorithm [13].
• nMDS embeds points in a euclidean
space in such a way that the distances
between points preserves the rank order
of the dissimilarity values betweenthose
points.
• it was found that two dimensions
provide an adequate embedding of the
similarity data

Emotion by dynamical simulation
• Essa & Pentland (1997): We describe a computer vision system for observing
facial motion by using an optimal estimation optical flow method coupled with
geometric, physical and motion-based dynamic models describing the facial
structure. Our method produces a reliable parametric representation of the
face’s independent muscle action groups, as well as an accurate estimate of
facial motion.
