  • Gait Analysis Through Computerized Sole Inspection
    Publication number: 20180256073
    Abstract: Disclosed herein are system, method, and computer program product embodiments for analyzing a person's gait through image analysis of the person's footwear. An embodiment operates by receiving an image associated with a shoe sole, the image displaying one or more cells forming part of a tread pattern of the shoe sole. The system then determining, based on the image, the wear levels of the cells and analyzes the wear levels to determine a wear pattern of the shoe sole. The system transmits information associated with the wear pattern for display in an interface of a computing device.
