  1. This table contains all of the geometric sample masks explored in this study. The columns of the table are sorted by the percentage number of samples. The rows of the table indicate a geometry class. We are interested in comparing the results of geometries across columns, as they can provide insight into the minimum number of samples that can be used that still allow us to obtain an acceptable level of SNR or mean SSIM index.
