  3. Persistent homology - Wikipedia

    en.wikipedia.org/wiki/Persistent_homology

    See homology for an introduction to the notation.. Persistent homology is a method for computing topological features of a space at different spatial resolutions. More persistent features are detected over a wide range of spatial scales and are deemed more likely to represent true features of the underlying space rather than artifacts of sampling, noise, or particular choice of parameters.

  4. Barcode library - Wikipedia

    en.wikipedia.org/wiki/Barcode_library

    Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.

  7. Persistence barcode - Wikipedia

    en.wikipedia.org/wiki/Persistence_barcode

    A persistence barcode is a complete invariant that captures all the topological information in a filtration. [2] In algebraic topology, the persistence barcodes were first introduced by Sergey Barannikov in 1994 as the "canonical forms" invariants [ 2 ] consisting of a multiset of line segments with ends on two parallel lines, and later, in ...

  9. Extended Channel Interpretation - Wikipedia

    en.wikipedia.org/wiki/Extended_Channel...

    The most common use for Extended Channel Interpretation is to allow usually unsupported national character sets such as Arabic, Greek, or Japanese to be used reliably in bar code symbols. [1] An ECI-enabled bar code symbol may use several character sets by embedding several character set ECI indicators to delimit segments of the message that ...
