The database systematically varies images across these categories:

: Images are captured from multiple angles using a horizontal semicircular camera array to simulate different head rotations. Cas Peal

: The full database includes 99,594 images, while a publicly available subset called CAS-PEAL-R1 contains 30,900 images. face pose angles

: The dataset provides metadata such as eye positions, face pose angles, and expression labels to help refine detection systems. Cas Peal

Researchers use this data to benchmark various algorithms, including Principal Component Analysis (PCA) and Local Binary Patterns (LBP) , ensuring they can handle the diverse conditions found in practical applications.
