Figure 1From: Wavelets filtering for classification of very noisy electron microscopic single particles images- application on structure determination of VP5-VP19C recombinantschematic diagram of reconstruction. A schematic diagram represents the principal operations for 3D reconstruction of a single particle. Starting by a particle selection and filtering operation, followed by classification to enhance the signal-to-noise ratio. Then an alignment is needed prior to average the particles in each class. The fourth operation is the orientation determination and the final operation is the 3D reconstruction.Back to article page
