Cas Peal Review

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 .

: Subjects are photographed wearing different accessories, including various pairs of glasses and different types of caps.

The database systematically varies images across these categories: Cas Peal

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

: The full database includes 99,594 images, while a publicly available subset called CAS-PEAL-R1 contains 30,900 images. is a large-scale Chinese face database created to

: Features images taken under 15 different lighting directions to test an algorithm's robustness to shadows and illumination changes. Database Specifications

: Includes various facial expressions such as neutral, smile, surprise, frown, and closed eyes. : The full database includes 99,594 images, while

The database was developed by the Joint Research & Development Laboratory (JDL) of the Chinese Academy of Sciences (CAS). Its primary purpose is to provide researchers with a robust dataset for training and testing algorithms against real-world visual challenges. Core "PEAL" Features
