Abstract

The invention discloses a semantic cognitive facial feature identification method, which comprises a semantic cognitive facial feature construction step: extracting a semantic cognitive facial feature, and establishing a mapping relationship between the semantic cognitive facial feature and a facial action unit; a semantic cognitive facial feature extraction and computing model designing step: establishing a hierarchical, dynamic and multi-resolution semantic cognitive facial feature extraction and computing model according to external physiological properties of a face; and a semantic cognitive facial feature extraction realization step: realizing facial action unit detection and semantic cognitive facial feature extraction by utilizing a plurality of levels of threshold values and a hidden markov algorithm. According to the method, human cognitive experiences are used for reference for the external information representation of the face, so that the external information description of the face is more consistent with the subjective consciousness of a person. The method is used in the field of human-computer interaction and in particular for behavior comprehension in the field of multi-modal human-computer interaction.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction behavior understanding, in particular to a recognition method for facial semantic recognition features. Background technique [0002] The human face contains a wealth of information. It is an important indicator that reflects human psychological activities. It is also a frequently used and indispensable way of expression in interpersonal communication. As an important non-verbal channel, it is very important for understanding the user's attitude and intention. irreplaceable important role. Therefore, the representation of facial explicitness has become an important research topic in the aspects of multimodal human-computer interface and action and behavior understanding under human-computer interaction. [0003] The current facial explicit representation methods can be divided into two categories: including symbolic description based on Facial Action Coding System (FACS: Facial...
