Synthetic Overlapping Slender Bodies (SOSB) Dataset

Overview The dataset is stored in `overlapping_slender.hdf5` and contains five groups, corresponding to the number of overlapping slender bodies: Groups: 1, 2, 3, 4 and 5 Images per group: 256 Image size: 128 × 128 pixels Each group contains: Field Description Shape input Grayscale images (256, 128, 128) labels Ground-truth splines (M×P×2 format) (256, M, P, 2) Where: M: number of slender bodies in each image (equal to the group number) P : number of control points per spline 2 : x and y coordinates Note: Only groups 1 through 3 were used in the experiments presented in the paper: Spline refinement with differentiable rendering. Groups 4 and 5 are included for possible future use or extended evaluation under more complex overlap scenarios. To open and visualize the dataset we provide a short script: python show_samples.py as well as two images (with and without labels) for quick inspection.
