Abstract

Facial expressions play a crucial role in depicting the thoughts and feelings of any human. Moreover, they might even serve as the distinguishing factor in categorizing whether a person is genuine or not. In this survey, the authors have carried out a systematic literature review of the past work done on facial emotion recognition and discrimination of genuine and fake emotions. Various datasets that are previously and currently being used in this field have been surveyed. The main objective of this paper is to study the state-of-the-art techniques that are being used to analyze and identify facial emotions and to distinguish between their genuineness. For this purpose, papers from distinguished publications have been researched and a comprehensive review of the literature has been fulfilled.
