Facial emotion recognition for Human-Computer Interactions using hybrid feature extraction technique

Abstract: Facial expression recognition is the most important criteria for effective Human Computer Interaction (HCI) as well as a medium to understand and communicate with children who cannot emote verbally. In this paper, we propose a feature extraction technique by embedding 2D-LDA and 2D-PCA. The features extracted were then tested on standard classifiers i.e., Support Vector Machine (SVM) and K-Nearest Neighbourhood (KNN) classifiers. Facial expression images from JAFFE and Cohn-Kennedy databases were utilized for training as well as testing. Very high facial emotion recognition rate of 97.63% and 94.8% has been obtained with the proposed method for JAFFE and Cohn-Kanade databases respectively.

1-(4,4''-Difluoro-5'-meth-oxy-1,1':3',1''-terphenyl-4'-yl)ethanone.

Abstract: In the title compound, C21H16F2O2, the central benzene ring is inclined at dihedral angles of 30.91 (8) and 46.88 (7)° to the two terminal fluoro-substituted rings. The dihedral angle between the two terminal fluoro-subsituted rings is 68.34 (8)°. An intra­molecular C—H⋯O hydrogen bond generates an S(6) ring motif. The crystal structure is stabilized by weak C—H⋯π inter­actions.
