Researchers have developed a novel video-based framework to passively count steps for individuals with Parkinson's disease, addressing limitations of current wearable-based methods. The system utilizes 3D human mesh recovery to estimate initial step counts from foot movement signals and refines these estimates using optical flow and cross-attention mechanisms to capture fine-grained gait dynamics. By employing multiple instance learning, the framework integrates clip-wise motion embeddings to predict residual step counts, demonstrating superior performance on real-world Parkinson's disease turning datasets.
