PCA Based Face Recognition System Using ORL Database
This package implements a well-known PCA-based face recognition method, which is called "Eigenface".
The program is easy to use. Furthermore, a sample Project file "ProjectPCA.m" is added that demonstrate how to use, ORL training and test database is also included to show Performance comparison for execution time and Recognition percentage, on different size of testing and training dataset.
