: The dataset provides metadata such as eye positions, face pose angles, and expression labels to help refine detection systems.
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. - HAL : The dataset provides metadata such
is a large-scale Chinese face database created to evaluate face recognition algorithms, specifically focusing on four key types of variations known as PEAL : P ose, E xpression, A ccessories, and L ighting .
: The full database includes 99,594 images, while a publicly available subset called CAS-PEAL-R1 contains 30,900 images. : The full database includes 99,594 images, while
: Features images taken under 15 different lighting directions to test an algorithm's robustness to shadows and illumination changes. Database Specifications
