To avoid the complex explicit feature extraction process in traditional expression recognition, a convolutional neural network (CNN) for the facial expression recognition is proposed. Firstly, the facial expression image is normalized and the implicit features are extracted by using the trainable convolution kernel. Then, the maximum pooling is used to reduce the dimensions of the extracted implicit features. Finally, the Softmax classifier is used to classify the facial expressions of the test samples. The experiment is carried out on the CK+ facial expression database using the graphics processing unit (GPU). Experimental results show the performance and the generalization ability of the CNN for facial expression recognition.
