摘要：

Plantar pressure image is an important tool for gait analysis. In the gait rehabilitation training of stroke patients, it can provide effective quantitative data reference for doctors to accurately assess the recovery status of patients and formulate targeted treatment programs. In this paper, a gait recognition algorithm for pressure sensing image is proposed. Through DBSCAN (Density-Based Spatial Clustering of Applications with Noise) clustering algorithm and minimum circumscribed rectangular algorithm, footprints can be accurately located in the pressure image for feature extraction. Three different degrees of abnormal gait and healthy gait are trained based on SVM (Support Vector Machine) algorithm. The training results can accurately identify the above abnormal gait, with an average accuracy of 91.4%.
