Summary

[edit]
Description
English: Scale-space kernels, comparing ideal discrete gaussian based on bessel function (red) with two-pole-pair forward/backward smoothers. Using alpha=1, t=1:5, pole position exp(-s) and exp(s) with s = sqrt(alpha*t)/4.

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “ScaleSpaceKernels.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
