• Abstract: Dynamic facial expression recognition has many useful applications in social networks, multimedia content analysis, security systems and others. This challenging process must be done under recurrent problems of image illumination and low resolution which changes at partial occlusions. This paper aims to produce a new facial expression recognition method based on the changes in the facial muscles. The geometric features are used to specify the facial regions i.e., mouth, eyes, and nose. The generic Fourier shape descriptor in conjunction with elliptic Fourier shape descriptor is used as an attribute to represent different emotions under frequency spectrum features. Afterwards a multi-class support vector machine is applied for classification of seven human expression. The statistical analysis showed our approach obtained overall competent recognition using 5-fold cross validation with high accuracy on well-known facial expression dataset.

  Existing facial expression recognition methods typically fine-tune a pre-trained visual encoder using discrete labels. We observe that the rich knowledge in text embeddings, generated by vision-language models, is a promising alternative for learning discriminative facial expression representations. We propose a novel knowledge-enhanced FER method with an emotional-to-neutral transformation.

  We put face forgery in a semantic context and define that computational methods that alter semantic face attributes are sources of face forgery. We construct a large face forgery image dataset, where each image is associated with a set of labels organized in a hierarchical graph. We propose a semantics-oriented face forgery detection method that captures label relations and prioritizes the primary task.

  We propose an identity and pose disentangled facial expression recognition (IPD-FER) model to learn more discriminative feature representation. For identity encoder, a well pre-trained face recognition model is utilized and fixed during training, which alleviates the restriction on specific expression training data. By comparing the difference between synthesized neutral and expressional images of the same individual, the expression component is further disentangled from identity and pose.

  Most of the current techniques for face recognition require the presence of a full face of the person to be recognized. In this work, we adopted the process of stitching the face by completing the missing part with the flipping of the part shown in the picture. The selected face recognition algorithms that are applied here are Eigenfaces and geometrical methods.
