Fourier Face Recognition

Face recognition implemented in MatLab using Fourier space algorithms as described in "Face Recognition in Fourier Space" by Hagen Spies and Ian Ricketts.

How to Run

Uncomment the desired functions in main() to run the program.

1. Run on the entire database and calculate accuracy:

correct = faceRecognitionTesting();
disp(['Face Recognition Accuracy: ', num2str(correct),'/400'])

2. Show example matches:

faceRecognitionShow()

3. Run on the entire database with rotated training images:

correct = faceRecognitionRotationTesting(angle);
disp(['Face Recognition Accuracy: ', num2str(correct),'/400'])

Change the argument in faceRecognitionRotationTesting(angle) to modify the angle the images are rotated.

4. Show example matches with rotated images:

faceRecognitionRotationShow(angle)

Results

Testing was done on the AT&T face database and achieved an accuracy of 97.75% (391/400).
