The 3D Emotion Recognition Using SVM and HoG Features

Abstract

Emotion recognition is becoming commercially popular due to the major role of analytics in various aspects of marketing and strategy management. Several papers have been proposed in emotion recognition. They are mainly classi¯ed in the past under 2D and 3D emotion recognition, out of which 2D emotion recognition has been more popular. Various aspects like facial posture, light intensity variations and sensor-independent recognition have been studied by di®erent authors in the past. However, in reality, 3D emotion recognition has been found to be more e±cient which has a broader area of use. In this paper, a 3D tracking plane with 2D feature points has enabled us to recognize emotions by statistical voting method from all planes having over threshold number of points in their respective contour area. The proposed technique's results are comparable to existing methods in terms of time, space complexity and accuracy improvement.
