Zero-shot denoising of microscopy images recorded at high-resolution limits
Fig 3
Results for blind zero-shot denoising short exposure TEM images of cilia (benchmark adopted from Bajic et al. [42]).
A: Qualitative comparison of denoised image sections showing a cilium (image sections chosen to match Fig 3 in [42]; image sections are scaled locally to fill the color range). B: Quantification of the denoising performance in terms of PSNR in dB and the BAD of the pseudo ground-truth (PGT) image and the denoised reconstruction (PSNR and BAD values plotted against each other). For the PSNR measure, we computed the difference (delta) between the values obtained for the reconstructed and the noisy image and here depict averages together with standard errors of the mean (SEM) over three independent executions of the experiment (note that the SEM values are very small and barely visible in the plot and that they were only evaluated for stochastic algorithms). Points are marked in red or blue if the blur effect value of the PGT image is larger or smaller than the blur effect value of the reconstructed image, respectively. Further details are discussed in the text.
