The recognition of basic facial expressions by neural network

摘要: An attempt is being made to develop a mind-implemented robot that can carry out intellectual conversation with humans. As the first step for this study, method perceive human emotion investigated. Specifically, of recognition from facial expressions by neural network shown. The authors categorized into six groups (surprise, fear, disgust, anger, happiness, and sadness) obtained 70 CCD (charge coupled device) camera-acquired data feature-points three components face (eyebrows, eyes, mouth). Then expression information generated input units network; learning are done backpropagation algorithm. >
