For all my lifters:
computer vision app to measure back curvature during deadlift!
main technical highlights:
— RF-DETR (Roboflow) to segment the person (great performance out-the-box with no additional training!)
— YOLO11n (Ultralytics) for bounding box prediction around the barbell weight plate (trained on my own small dataset).
— Mediapipe (Google) for pose landmark detection to guide the bounds for the line fitting.
— Custom logic to fit a line across the back.
about the plots on the right side:
The Back Roundness Map shows the deviation of the estimated back curve from a line of best fit.
