Facial
expression recognition (FER) is emerging as an emerging and multifaceted field
of study. The use of FER in areas such as healthcare, security, and safe
driving has not only enhanced the credibility of these technologies, but also
their integration into human computer interaction to achieve intelligent
outcomes. Computational FER seeks to replicate the skill of humans in decoding
facial expressions, providing important cues that complement spoken language
and aid listeners in understanding. Likewise, FER's deep learning (DL) and
Artificial Intelligence (AI) methodologies are meticulously designed,
incorporating advanced modules for efficiency and real time processing. In
light of this background, many investigations have looked at different aspects
of FER. Although current surveys focus primarily on traditional technologies
and generic methodologies for on premises servers, they overlook the large
field of deep learning inspired by edge vision and AI assisted FER
technologies. To fill this gap, the current study conducts a comprehensive and
thorough analysis of the prevailing FER literature. It carefully surveys the
operational framework of FER technologies, highlighting their basic and
intermediate phases, as well as the underlying pattern structures. Furthermore,
the study addresses the limitations inherent in current FER surveys. The
exploration extends to the FER datasets, subjecting them to thorough
examination, thus revealing the attendant challenges and pitfalls. In addition,
it provides a comprehensive discussion of the various metrics used to measure
the effectiveness of FER methods.
