Abstract: Highlights•An algorithm to improve kinematics accuracy in markerless gait analysis is presented.•This algorithm refines AI-driven skeletons in a subject-specific geometric manner.•It preserves skeleton links’ length during walking, using intra-frame modelization.•It benefits from gait phases information in between-frames adjustments.•It smooths lower limb joints’ trajectory in between-frames adjustments.
