Abstract

Given the critical role that facial expressions play in human connection and communication, facial expression detection and recognition have attracted a lot of interest recently. The numerous uses of facial expression detection in a variety of industries, including virtual reality, intelligent tutoring systems, healthcare, and data-driven animation, are largely responsible for this spike in interest. The primary objective of facial expression recognition is to precisely recognise people's emotional states from a variety of face photographs. These states include anger, contempt, disgust, fear, happiness, sadness, and surprise. This research focuses on the detection and recognition of facial expressions using the Viola-Jones algorithm. The Viola-Jones method provides a strong framework for evaluating facial features and identifying nuanced expressions across various scales and orientations. It is well-known for its efficiency and effectiveness in object detection. Facial expression detection and recognition are made possible by the Viola-Jones algorithm, which also improves the functionality of other technological systems and advances human-computer interaction. With its ability to accurately and efficiently analyse human emotions, the Viola-Jones algorithm has the potential to revolutionise a wide range of industries. This study intends to investigate the application of this algorithm in the recognition of facial expressions.
