3D Digital Twin Visualization of Multiclass GRF-Based Gait Disorder Classification

The paper presents a new framework that classifies healthy gait and multiple musculoskeletal impairment groups using bilateral ground reaction force (GRF) and center-of-pressure (COP) signals. After normalizing and standardizing the signals, the model achieved 99.00% validation accuracy and 90.07% test accuracy with a session-level split. The approach includes class‑specific ε‑LRP explainability and synchronizes processed GRF signals with model predictions in a Blender‑based 3D visualization for sample‑level inspection.

Vocabulary-Guided Gait Recognition

The paper introduces Vocabulary‑Guided Gait Recognition (Gait‑World), a new paradigm that leverages human vocabularies and Vision‑Language Models (VLMs) to better understand and recognize gait. It proposes the α‑Gait model, which uses a Vocabulary Relation Mapper and a Gait Fine‑grained Detector to align vocabulary prompts with gait features, addressing the challenge of heterogeneous embedding spaces. Experiments on multiple gait datasets demonstrate the potential of incorporating VLM‑derived vocabulary information into gait recognition.

Occluded Gait Recognition with Mixture of Experts: An Action Detection Perspective

The paper introduces GaitMoE, an action‑detection based mixture‑of‑experts framework for occluded gait recognition, leveraging temporal and action experts to infer missing body parts from adjacent frames and gait cycles. It also presents a new Occluded Gait database (OccGait) with diverse occlusion scenarios and annotations, and demonstrates superior performance on OccGait, OccCASIA‑B, Gait3D, and GREW datasets.
