Root link of the proposed FWD-GCA-based metric: 10.6084/m9.figshare.15020151.

Results of angular distortions of traditional differential-based (10.6084/m9.figshare.15022074), GCA and the proposed FWD-GCA (10.6084/m9.figshare.15022092) metrics for 1 million sample points (10.6084/m9.figshare.15035457).

These results are generated by 'eval_1M.jl' in 10.6084/m9.figshare.15022095, and compressed as ZIP files.

Unzip all files to a folder named 'img_data_angular', and use 'plot_1M.py' and unzipped CSV format for further plotting (results of plots: 10.6084/m9.figshare.16681909).
