Denoising of Images from Electron Microscope
 Holub, Zbyněk ; Kolář, Radim (oponent) ; Odstrčilík, Jan (vedoucí práce)
This master’s thesis is focused on the image denoising of images acquired by transmission electron microscope. Thesis describes principles of TEM image digitizing. It also describes the types of noises, which are the unwanted part of final image and they can damage it. Therefore, filtration methods based on total variation minimizing were chosen and used for TEM image denoising in this thesis. Non-local means filter, chosen for filtration quality comparison, because nowadays this filter is the-state-of-art in denoising methods. Filters were tested on artificially noised images by Gaussian and Poisson noise and also on images from TEM microscope. TEM images were acquired with different electron dose and with different binning. The results of filtration quality are rated by these benchmarks – SNR, PSNR and SSIM. All obtained results are shown in figures and they are discussed in the practical part.
