CASIA-B Pose

Gait recognition as a prominent field within biometrics and computer vision focuses on analyzing the unique walking patterns of individuals for identification and security purposes. CASIA-B dataset encompasses a diverse collection of gait patterns with variations in walking styles, clothing, and viewpoints. This rich variety enables researchers to train and evaluate gait recognition algorithms on a comprehensive dataset that reflects real-world scenarios. Additionally, pose holds its own advantage in terms of robustness against carrying objects and clothing, making it particularly attractive for practical applications. However, most pose-based gait recognition methods tend to employ pose benchmarks calculated with different pose estimation algorithms, which led to duplicated work and biased comparisons. Hence, we introduce CASIA-B Pose, a pose-based gait recognition benchmark that utilizes 17 keypoints extracted by two state-of-the-art pose estimation algorithms, i.e. HRNet[1] and SimCC[2]. We also provide the mapping relations between RGB frames and keypoint tensors to foster further development.
