| Abstract(in English) | Dynamic facial expressions (i.e., video sequences of facial expressions) were investigated using a stereo-camera system and generalized Procrustes analysis (GPA). Two undergraduate students provided facial videos. Prior to each recording, the positions of 19 feature points were marked by blue dots on each face. Each participant played UNO game with two opponents. Facial sequences of each participant were captured during the game using two video cameras. 3D coordinates of the feature points of each frame were obtained by triangulation. In order to standardize them, we performed GPA on facial feature points separately for each participant. Moreover, principal component analysis (PCA) was performed on standardized facial coordinates for each participant. For both participants, the 1st PCs were found to be related to mouth opening, indicating that the 1st PCs were linked to laughing. Time sequential pattern of laughing was examined based on time series of the PC1 scores. |
