英文摘要： Violence is on the rise around the world. In order to advance warning of it, researchers began to pay more and more attention to the area of automatic identification and warning of dangerous behavior. Micro-expressions are inadvertently showing of human expression and lasts only 1/25-1/5 seconds. Micro-expressions reveals a person's true intentions, and is one of important clues of the detection process to prevent dangerous behavioral. This project intends to study and propose algorithms and technology for human-like emotional analysis and its application in warning of dangerous behavior based on micro-expressions. Main research contents include: 1) To propose an efficient Micro-expression detection algorithms to detect and locate Micro-expression in high-speed, high-definition video; 2) To propose robust Micro-expression feature extraction algorithms to extract robust features from facial and body motion videos, these features should be effective for next step of emotion analysis and warning of dangerous behaviors; 3 ) To design an artificial intelligent model to fuse the expert knowledge and multi-mode features extracted in step 2 , the final purpose is to implement system of human-like emotion analysis and warning of dangerous behavior. This project of the Micro-expression feature extraction and analysis technology is a cross-cutting research project involving multiple disciplines of computers, signal and information processing and clinical psychology, has important theoretical and practical significance, and may contribute promote mutual exchanges in various research areas and promote the development of related technologies.
