1. ECE533 – Image Processing Project Face Recognition Techniques

3. Entertainement: Virtual Reality
Smart Cards: Drivers’ license
Law Enforcement: CCTV control
Info Security: Parental Control

4. Algorithm 1: Face recognition using eigenfaces
Calculate eigenfaces from the set of images
New image  calculate its set of weights.
Determine if the image is a face.
Determine if the image corresponds to a known face of the database of not.

5. Correlation matrix:
Vector of weights:
Euclidean distance:

6. Algorithm 2: Face recognition using line edge map
It represents face features
Sobel edge detection algorithm
Low memory requirements
