How AI Reads Facial Expressions

Three steps from pixel values to psychological affect classification.

1

1. Micro-Movement Mapping

The convolutional neural net scans 68 landmark coordinates across the brows, eyes, and mouth.

2

2. Action Unit Scoring

It calculates muscle contraction vectors based on the Facial Action Coding System (FACS).

3

3. Probability Distribution

A softmax layer generates a 100% probability curve across all 7 universal emotions.
