swift-body-reshape

On-device, license-clean body reshaping for photos and video — Vision body pose tracking + Core Image warps (slim waist, chest, arms). No generative model.

Status: spike. The pose tracker + a skeleton-grid debug overlay are in; the reshape warps come once the pose is validated on unobstructed torso footage. A face-focused close-up (mic/cup occluding the torso) tracks shoulders/neck well but the arms and lower torso are unreliable — reshape needs a half/full-body shot.

• BodyPose / BodyPoseFrame / BodyPoseTrack — Codable model + interpolation.
• BodyPoseTracker — VNDetectHumanBodyPose, strongest person, ~4 fps, smoothed.
• Debug: BODY_RESHAPE_RENDER=1 swift test writes ~/Downloads/body_pose_skeleton.png.

Requirements

macOS 26 / iOS 26, Swift 6.2.
