Facial expressions are used by humans to convey their mood and emotional state to others. A listener grasps more efficiently speaker’s intentions and the content communicated to him/her, if he/she can observe speaker’s facial expressions, which complement speech prosody. Human facial expressions have a complex structure, requiring a good amount of time and practice to be decoded by the human brain, as well. Resorting to recent advancements in computer vision and machine learning, many researchers have promoted the state-of-the-art in facial expression recognition and have successfully exploited them in application domains, such as medical treatment, driver behavior analysis, and sociable robots deployment.
Earlier, researchers believed in that human facial expressions (e.g., the so-called six primitive emotions) remain invariant to cultural differences. But soon, it has been found out that there is no universal model of facial expressions and there are many deep facial expressions, which are affected by different factors.
Closely related to facial expression recognition, is understanding aging, which affects human face appearance in a progressive and accumulative manner. Although the effects of aging on human face are diverse and subject-dependent, some aging patterns, such as the formation of thin lines around eyes and/or mouth and the alteration of skin texture, are common across individuals. If these aging patterns are successfully learned, they can be exploited to simulate aging and generate subsequent face appearance (face age progression) or precedent face appearance (face age regression or rejuvenation). An efficient face aging method should produce realistic face aging results while maintaining personality, i.e., facial characteristics unique to everyone. Simulation of face age progression and regression is useful in security related applications, such as age invariant face recognition.
Recent advances in deep learning and artificial intelligence have contributed to understanding better facial expressions and advancing the performance of machine learning and/or synthesis tasks associated to face images. Deep learning basically tries to collect many small contributing features from a large human face image dataset (e.g., a dataset of human facial expressions). By doing so, it is ensured that even a small change can be recognized by the camera, which might get missed by human eyes also. Deep learning pipelines can be exploited in multiple application domains, such as biometrics, forensics, surveillance, medical treatment, social understanding, human-computer interaction. The correct recognition of feeling can enhance the security of biometric system. For example, a “feared face” can be declined to provide entry in a secured place even if face ID is correct.
The goal of this special issue is to gather highly novel contributions by prominent research scholars (either academicians industry professionals), which will shed light to deep learning techniques applied to faces and will advance related domain applications.
