What is Face Image Retrieval: PCA vs. Wavelet Methods about?

The document compares the performance of three techniques for face image retrieval from a database: principal component analysis (PCA), discrete wavelet transform with PCA (DWT-PCA), and lifting wavelet transform with PCA (LWT-PCA). It implements these techniques on images from the ORL face database and finds that LWT-PCA performs best with lower computation than PCA or DWT-PCA, while DWT-PCA achieves high retrieval rates.
