- Abstract:
-
The expression recognition model shows significant performance differences between datasets due to subjective annotation and objective condition differences in the collection of facial expression datasets. A domain adversarial network model based on expression fusion features is proposed for cross-dataset facial expression recognition. This model aims to improve the accuracy of cross-dataset expression recognition and reduce the sample marking and retraining processes for expression recognition in practical applications. Residual neural networks are used to extract the global and local features of facial expressions. An encoder module is then employed to fuse global and local features to learn deep expression information. A fine-grained domain discriminator is adopted to antagonize the source dataset against the target dataset, aligning the edge and conditional distributions of the dataset and facilitating the migration of the model to the unlabeled target dataset. RAF-DB is used as the source dataset, and CK+, JAFFE, SFEW2.0, FER2013, and Expw are used as the target datasets for cross-dataset facial expression recognition experiments. Compared with other cross-dataset facial expression recognition algorithms, the proposed method achieves the highest average recognition rate. Experimental results show that the proposed method can effectively improve the performance of cross-dataset facial expression recognition.
