Lift Vision Lab V2

Run a pretrained person detector on a sample chairlift clip or your own video. The browser downloads the model and processes the selected video on your device.


Choose one continuous shot. Each person in view counts a track once after three detections. Optionally drag a rectangle around the off-ramp to exclude people outside it, or click the preview to reset the region.

Choose a sample or local video to start.

Counted people

Click a timestamp to review its sampled frame. A long occlusion or re-entry can create a second track for the same person. A person detection can be a rider or a bystander. Review the events before using the count. Equipment and patrol are unclassified.

Coat color is estimated from the upper body across several frames. Use the menu to correct it after reviewing the clip.
