Suffocate infant behaviour recognition scheme based on neural network classifier

摘要

This paper come out with an infant behaviour recognition scheme based on neural network. In this study, the infant face region is segmented based on the skin colour information. Two types of features, namely Singular Value Decomposition (SVD) and Power Spectrum are then calculated based on the information available from the infant face regions. Since each type of features in turn contains several different values, given a single fifteen-frame sequence, the correlation coefficients between those features of the same type can form the attribute vector of pain and normal facial expressions. Fifteen infant facial expression classes have been defined in this study. Neural Network corresponding to each type of those features has been constructed in order to classify these facial expressions. The experimental results show that the proposed method is robust and efficient. The properties of the different types of features have also been analyzed and discussed.
