Fig. B.1.

DSSIM and nCCC variation study. Top panel: ground truth images for Kerr a* = 0.6, Kerr a* = 0.94 and dilaton black holes (left most column) and convolved with decreasing beams (30 μas–1 μas). Middle panel: DSSIM and nCCC calculations using the average image of Kerr BH with a* = 0.6 as ground truth image. Bottom panel: DSSIM and nCCC calculations using the average image of Kerr BH with a* = 0.94 as ground truth image.
