- Delaunay triangulation: Two implementations of the Delaunay triangulation are now available which share the same interface. The new implementation (Guibas-algorithm) is roughly ten times faster than the previous version (based on Chew‘s algorithm).
- 2D Geometry: Packages
imagingbook.pub.geometryhave been revised. A new interface
Pointhas been added to handle various implementations of 2D points across different packages.
- Discrete Fourier and Cosine Transforms: The DFT and DCT libraries (packages
imagingbook.pub.dct) and associated ImageJ plugins (in
imagingbook_plugins_all/Spectral_Techniques). Added fast implementations based on the
JTransformspackage by Piotr Wendykier. Note that these are efficient mixed-radix implementations of the FFT that are not restricted to image sizes that are powers of two and thus require no image padding!
- ImageJ plugins for book chapters: Maintenance of the plugin collections for all previous book editions has become too tedious. These sub-modules were thus frozen and will not be maintained (i.e., adapted to new releases of the
imagingbook-commonlibrary) any longer. A complete and continuously updated collection of plugins is contained (as before) in the imagingbook-plugins-all repository. ZIP files with the plugin sets for previous book editions are found in the new plugins-archive.
- Miscellaneous: The Maven dependency setup has been simplified by automatically copying all required runtime-dependencies to ImageJ’s jar folder.
