Face Identification
Agenda
Why Face Identification?
• Useful• Interesting• Creating own dataset for extra credits
Data set
• The Extended Yale Face Database B– 2414 images of 38 human
• Own data – 100 images of 4 people
Classifiers
• SVM (Support Vector Machine)– LIBSVM– Self Implemented SVM Optimizer
• ANN (Artificial Neural Network)
• Coded in Matlab
Classifier Parameters
• SVM – Kennel functions
• ANN – Layers and units
Feature Selection
• Raw pixels• Down-sampling pixels • Extracted features
