Tracking Suspicious Behaviour Using Facial Expression Recognition Techniques: A Survey
نویسندگان
چکیده
Nowadays, facial expression detection and expression recognition has become one of the most important topics in research field. Facial expressions may be used to identify criminals. In today’s scenario, the crime rate is increasing day-by-day and criminals are set free due to lack of evidence. Investigators often express confidence in their potential to spot a lie. But identifying a criminal who is lying is very difficult task. This paper aims at listing the steps of the lie detection of criminals using facial expression recognition technique and various algorithms that are used

متن کاملImproving LNMF Performance of Facial Expression Recognition via Significant Parts Extraction using Shapley Value
Nonnegative Matrix Factorization (NMF) algorithms have been utilized in a wide range of real applications. NMF is done by several researchers to its part based representation property especially in the facial expression recognition problem. It decomposes a face image into its essential parts (e.g. nose, lips, etc.) but in all previous attempts, it is neglected that all features achieved by NMF ...
