Forward model indexing allows users to maximize the information extracted from their data but historically has a steep learning curve. Hough indexing is well established but susceptible to poor pattern quality. Spherical harmonic-based indexing combines the robustness of forward model indexing … See more Dictionary indexing compares experimental electron backscatter diffraction (EBSD) patterns against a dictionary of simulated patterns for each orientation on a uniform grid in orientation space [1,2]. Synthetic … See more Spherical indexing can be used on EBSD patterns with a wide range of patten quality. In this example, a set of scans of the same region on a … See more WebThe relative advantages and disadvantages of pattern matching techniques, such as Dictionary Indexing or Spherical Indexing, have been discussed in the “Techniques for Indexing” page, but here we focus on conventional Hough-transform based indexing. AZtecHKL uses a robust indexing method termed “Class Indexing”.

Notable features of the library include: Flexible support for spatial indexing, including the ability to approximate arbitrary regions as collections of discrete S2 cells. This feature makes it easy to build large distributed spatial indexes.
WebThe rule is the following. The even Zernike polynomials Z (with even azimuthal parts (), where = as is a positive number) obtain even indices j.; The odd Z obtains (with odd azimuthal parts (), where = as is a negative number) odd indices j.; Within a given n, a lower results in a lower j.; OSA/ANSI standard indices.
