Abstract
This research aims to improve the anatomical accuracy of 2D human pose estimation models by enhancing the level of detail in the skeletal representation, particularly for the spine region. The research is guided by two main objectives: (1) to identify which of three widely used deep learning models (OpenPose, MediaPipe BlazePose, or MoveNet) most accurately predicts keypoints by comparing model outputs with Inertial Measurement Unit (IMU) data; and (2) to develop a curve-fitting algorithm using Bezier and B-Spline formulas to create realistic spine curvature based on new spine keypoints.
