Project 5: Recognition of facial expressions
Objective: You have a database of faces shot for each subject with two expressions: serious and smiling. The goal is to build a system for the automatic recognition of facial expressions (serious/smiling).
Method:
- Inspecting the structure of the dataset (PCA or similar)
- Develop binary classifiers (Bayesian and logistic classifier models) that
correctly associate expression (serious, smiling) with face.
- Analyze the classifiers performance (% of correct decisions, sensitivity,
specificity, AUC) and determine what classifier model is best.
- Use LDA to identify which image features are most important for
discrimination.
Bonus: Using the same approach, build a classifier that can also distinguish the person's gender in addition to their expression.
