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). [ 2 ] [ 3 ] Its first version, ImageJ 1.x, is developed in the public domain , while ImageJ2 and the related projects SciJava , ImgLib2 , and SCIFIO are ...
The Abeles matrix method [3] [4] [5] is a computationally fast and easy way to calculate the specular reflectivity from a stratified interface, as a function of the perpendicular momentum transfer, Q z: = =
Data may be multiple photographs, data from different sensors, times, depths, or viewpoints. [1] It is used in computer vision, medical imaging, [2] military automatic target recognition, and compiling and analyzing images and data from satellites. Registration is necessary in order to be able to compare or integrate the data obtained from ...
While Fiji was originally intended for neuroscientists (and continues to be so [8]), it accumulated enough functionality to attract scientists from a variety of fields, such as cell biology, [9] parasitology, [10] genetics, life sciences in general, materials science, etc.
The formation of the virtual image A' of the object A via a plane mirror. For people looking at the mirror, the object A is apparently located at the position of A' although it does not physically exist there. The magnification of the virtual image formed by the plane mirror is 1. Top: The formation of a virtual image using a diverging lens.
This threshold is determined by minimizing intra-class intensity variance, or equivalently, by maximizing inter-class variance. [2] Otsu's method is a one-dimensional discrete analogue of Fisher's discriminant analysis , is related to Jenks optimization method , and is equivalent to a globally optimal k-means [ 3 ] performed on the intensity ...
higher intra-class variance than inter-class variance, i.e., pixels from a same group have closer intensities to each other than to pixels of another group, homogeneous lighting, etc. In difficult cases, thresholding will likely be imperfect and yield a binary image with false positives and false negatives.
MIP Display was invented for use in Nuclear Medicine by Jerold Wallis, MD, in 1988 at Washington University in St. Louis, and subsequently published in IEEE Transactions on Medical Imaging. [2] In the setting of Nuclear Medicine, it was originally called MAP (Maximum Activity Projection). [3] [4]
