Reconstructions with different sampling numbers. (a) Fully sampled image, (b) zero-filled images and sampling masks. (c,d,e,f,g) for 1, 5, 10, 20 and 40 samples for reconstructions. Images are generated by taking the average of multiple samples. Corresponding uncertainty maps are shown under each image. The numbers on the lower left of each image indicate PSNR and SSIM, respectively.
