From: Probabilistic brain MR image transformation using generative models
Response of models to out-of-distribution (OOD) input images. Column 1: input image; column 2: target image (when available); column 3-4: output and standard deviation images for the cGAN model; columns 5-6: transformed image and standard deviation for NCSN; columns 7-8: transformed image and standard deviation for DDPM. Rows 1, 2, and 3: images with RF zipper, reconstruction artifact, and low SNR; rows 4-5: images with brain tumor and white matter MS lesion pathologies.
