| Currently, human age estimation and gender classification are used in several tasks, such as public safety, video surveillance, and access control. A persons gait is a unique behavioral biometric that cannot be faked. It allows evaluating the age and classifying the gender of a person based on video recordings taken from a long distance and low-resolution images. The main challenges associated with recognizing a person by gait include wearing accessories and variations in clothing. Also, the shape of the silhouette makes it easier to distinguish between a male and a female, but the obtained image may not contain enough information to determine age. In this paper, we propose an approach based on transfer learning that aims to address these issues. The sinogram of the Radon transform from the gait energy image is fed into the Mobilenet and Densenet models. This procedure is applied in the feature extraction stage. They operate in parallel. Local Zernike moments are also extracted and fused with features from deep neural networks. The hML-KNN classifier, which combines the extracted features, is applied to improve the proposed approachs accuracy. The proposed method is evaluated on two datasets: CASIA-B and OUISIR OULP-Age. Explainable artificial intelligence with Grad-CAM is used to visualize the proposed models performance. The experimental results were compared with other well-known models. The approach demonstrated high efficiency, achieving an average accuracy of 99.25% for the CASIA-B dataset, 95.35% for the female class, and 94.93% for the male class across different age groups for the OU-ISIR OULP-Age dataset. The application and development of the proposed approach will improve the functionality of automated information systems in the medical, law enforcement, and banking sectors and help experts in decision-making. | |
