Fig. 4

Denoising of an electron microscopy projection with Poisson noise. Small magnified patch is shown below for detailed analysis, where this patch is indicated in b. In a and c are the original image, with little noise, and in b and d are the simulated noisy images. In e is the TV denoised image, in f is the HOTV denoised, in g is the MHOTV denoised, and in h is the shearlet denoised by hard thresholding. One-dimensional plots of a single cross-section are shown on the right for an additional point of comparison
