Title: Audio Visual Emotion Recognition Using CrossCorrelation and Wavelet Packet Domain Features
Abstract: The better a machine realizes non-verbal ways ofcommunication, such as emotion, better levels of human machine interrelation is achieved. A method forrecognizing emotions from human Speech and visual data formachine to understand will be described. For extraction of features, videos consisting6 classes of emotions (Happy, Sad, Fear, Disgust, Angry,and Surprise) of 44 different subjects from eNTERFACE05database are used. As video feature, Horizontal and VerticalCross Correlation (HCCR and VCCR) signals, extracted fromfacial regions - eye and mouth, are used. As Speech feature, PerceptualLinear Predictive Coefficients (PLPC) and Mel-frequencyCepstral Coefficients (MFCC), extracted from Wavelet PacketCoefficients, are used in conjunction with PLPC and MFCCextracted from original signal. For both types of feature, KNearestNeighbour (KNN) multiclass classification method isapplied separately for identifying emotions expressed in speechand through facial movement. Emotion expressed in a video fileis identified by concatenating the Speech and video features andapplying KNN classification method.
