Random Dot Stereogram (rds4) Dataset with Border Ownership Annotation

# Annotations for a Random Dot Stegrams (rds4) dataset - This repository contains annotations for a Random Dot Stereograms (rds4) dataset. These annotations were developed to support research in **border ownership representation**, **disparity-based segmentation**, and **figure-ground organization** in synthetic depth stimuli.- The dataset was generated using a modified version of the RDS generation method by Marino (2007): https://www.mathworks.com/matlabcentral/fileexchange/14859-stereogram > NOTE: This dataset complements the previously released > Chen T. (2025). *Border Ownership and Category Annotation Extended from Virtual KITTI 2* [Data set], > Zenodo DOI: [https://doi.org/10.5281/zenodo.15375453](https://doi.org/10.5281/zenodo.15375453) --- ## Contents This dataset provides the following additions:- **Border ownership maps** — 2-channel directional annotations representing ownership along contours (Chen et al., 2022)- **Disparity maps** — Absolute (Far/Near) disparity representations (Chen et al. 2025)- **Instance-level contour maps** — Extended labeling for object-level border continuity- **Scripts** — MATLAB and Python utilities to read, write and display `.flo`-formatted annotations > For a complete specification of annotation file formats, see [DATAFORMAT.md](./DATAFORMAT.md). --- ## License This dataset is released under the **Creative Commons Attribution-ShareAlike 4.0 International (CC-BY-SA 4.0)** license.
