Effect of emotional expressions on facial landmark-based face recognition

Key Points

• This research investigates how different emotional expressions influence the accuracy of facial recognition.
• Analyzed various facial landmarks for recognition tasks.
• Utilized emotional expression datasets to test recognition accuracy.
• Employed computer vision algorithms for assessing face recognition performance.
• Facial expressions significantly impacted recognition accuracy.
• Emotionally neutral faces were recognized less accurately than those with distinct emotional expressions.
• Recognition accuracy varied from 60% for neutral to over 80% for expressive faces.
