Crystallographic image processing (CIP) is traditionally understood as being a set of key steps in the determination of the atomic structure of crystalline matter from high-resolution electron microscopy images obtained in a transmission electron microscope that is run in the parallel illumination mode.
The multiple crystals on the right were grown from a sugar cube, while the one on the left was grown from a single seed taken from the one on the right. Red dye was added to the sugar solution before growing the large crystal, but was insoluble with the sugar in its solid state, and all but small traces of the dye was forced to precipitate out ...
Microscope image processing is a broad term that covers the use of digital image processing techniques to process, analyze and present images obtained from a microscope. Such processing is now commonplace in a number of diverse fields such as medicine , biological research , cancer research , drug testing , metallurgy , etc.
ImageJ is a Java-based image processing program developed at the National Institutes of Health and the Laboratory for Optical and Computational Instrumentation (LOCI, University of Wisconsin).
In geology, phase contrast is exploited to highlight differences between mineral crystals cut to a standardised thin section (usually 30 μm) and mounted under a light microscope. Crystalline materials are capable of exhibiting double refraction , in which light rays entering a crystal are split into two beams that may exhibit different ...
The crystals are captured, stored, and sputter-coated with platinum at cryo-temperatures for imaging. The crystallization process appears to violate the second principle of thermodynamics. Whereas most processes that yield more orderly results are achieved by applying heat, crystals usually form at lower temperatures – especially by ...
Image SXM is an image analysis software specialized in scanning microscope images. It is based on the public domain software NIH Image (now ImageJ from the National Institutes of Health ) and extended to handle scanning microscope images, especially of the SxM formats (SAM, SCM, SEM, SFM, SLM, SNOM, SPM, STM), hence its name.
Under ideal conditions, this produces an "hourglass" shape of this point source in the third (axial) dimension. This shape is called the point spread function (PSF) of the microscope imaging system. Since any fluorescence image is made up of a large number of such small fluorescent light sources, the image is said to be "convolved by the point ...
