Every step.
Every phase.
Every stride.

ConductVision applies a Hidden Markov Model over per-foot contact and joint kinematics to produce smooth, gap-free temporal segmentation — turning a single sagittal video into stride-locked gait data.

  • Bilateral heel-strike / toe-off event detection
  • Cycle-aware smoothing eliminates flicker frames
  • Stride length, cadence, double-support, symmetry — one model
  • Exports CSV, C3D and clinical-report-ready summaries

Workflow

From a single video to stride-locked gait data

1

Record standard video

Use a single sagittal camera in a hallway, lab walkway, rehabilitation setup, or controlled motion protocol — no force plate or wearable sensors.

2

Decode with the HMM

A 4-state Hidden Markov Model reads per-foot contact and joint kinematics frame by frame, then smooths across the temporal sequence for gap-free stride boundaries.

3

Export reproducible metrics

Stride length, cadence, double-support, and symmetry export to CSV, C3D, and clinical-report-ready summaries you can take straight into statistics.

Applications

Metrics built for clinical and translational gait

The same HMM decoder powers human mobility studies and sits beside rodent gait and animal-behavior analysis, keeping a common video and export workflow across translational programs.
