摘要

Parkinson’s disease (PD) is a neurodegenerative disorder characterized by progressive motor impairments, prominently reflected in gait abnormalities. This study presents a preliminary investigation using the newly developed Parkinson’s Disease Gait Video (PDGV) dataset to evaluate the discriminative capacity of gait features to distinguish PD patients from healthy controls. The goal is to support the development of noninvasive, vision-based diagnostic tools through effective feature extraction and classification techniques. Experiments conducted on Gait Energy Images derived from PDGV demonstrate that appearance-based representations combined with deep convolutional neural networks can effectively capture pathological gait patterns. The investigation of the performance of VGG, AlexNet, DenseNet, and ResNet from \(0^{\circ }\) 0 , \(90^{\circ }\) 90 , and \(180^{\circ }\) 180 view angles showed that ResNet-101 is the most performant model, achieving accuracy, precision, recall, and F1-score of 0.81, 0.84, 0.64, and 0.73, respectively, from the \(90^{\circ }\) 90 view angle. These findings underscore the potential of gait-based analysis for automated PD screening and provide a foundation for future intelligent assistive diagnostic systems.
