Abstract :
Cryoelectron tomography attempts to allow the visualization of complex biological specimens´ molecular architecture. This technique yields 3D maps with an extremely low signal-to-noise ratio. A new approach based on anisotropic nonlinear diffusion offers a strategy to reduce the noise and enhance local structures.
