Structural studies by electron tomography: from cells to molecules.
TL;DR: In combination with advanced computational methods, such as molecular identification based on pattern recognition techniques, cryo-ET is currently the most promising approach to comprehensively map macromolecular architecture inside cellular tomograms.

TL;DR: Cryoelectron tomography is used to visualize the 3D structures of 110 individual virions of the X-31 (H3N2) strain of influenza A, and some virions have substantial gaps in their matrix layer, and others appear to lack a matrix layer entirely, suggesting the existence of an alternative budding pathway in which matrix protein is minimally involved.

TL;DR: First-photon imaging is introduced, which is a computational imager that exploits spatial correlations found in real-world scenes and the physics of low-flux measurements, and recovers 3D structure and reflectivity from the first detected photon at each pixel.

Scale-space and edge detection using anisotropic diffusion
Pietro Perona,Jitendra Malik +1 more
TL;DR: A new definition of scale-space is suggested, and a class of algorithms used to realize a diffusion process is introduced, chosen to vary spatially in such a way as to encourage intra Region smoothing rather than interregion smoothing.

Bilateral filtering for gray and color images
Carlo Tomasi,Roberto Manduchi +1 more
TL;DR: In contrast with filters that operate on the three bands of a color image separately, a bilateral filter can enforce the perceptual metric underlying the CIE-Lab color space, and smooth colors and preserve edges in a way that is tuned to human perception.
