Abstract

The invention discloses a Capsule-Net-based face expression recognition method. The method comprises: step one, selecting a data set and selecting a Cohn-Kanade Plus Database expression data set, thatis, a CK+ expression data set; step two, selecting a deep learning model and using a deconvolution-version Capsule Net as an experimental model; step three, carrying out training and testing based onthe model, segmenting the CK+ expression data set into a training data set and a test data set, reading the training data set into the Capsule Net for periodic training to obtain a stable and accurate Capsule Net deep learning model; and step four, combining the trained Capsule Net deep learning model with an NAO robot, tracking the training process in real time by the NAO robot, reporting information related with the model testing regularly, and expressing an image recognition result in a voice and gesture manner. Therefore, convergence is realized quickly within short time; and the facial expression recognition accuracy and the reliability are improved.
