Fig. 1From: Iterative Bayesian denoising based on variance stabilization using Contourlet Transform with Sharp Frequency Localization: application to EFTEM imagesCentral plane (number 31 of sections 0 to 63) of the reconstructed volume before denoising. The gray levels are voxels proportional directly to the quantity of the present iron. a cytoplasm, b resin, c iron aggregate area d iron aggregates on the cell wall which are considered as the useful signal and is used to evaluate the different algorithmsBack to article page
