Recent Changes

  • [2021/01/19] Release 1.9. Completely revised GenericFilter framework with new (float-based) PixelPack and PixelSlice containers for arbitrary image data. New mechanism (ProgressMonitor and ProgressReporter) for simple, asynchronous progress reporting during prolonged operations. Concrete filter classes have been revised and adapted.

  • [2020/12/27] Release 1.8. Region segmentation API revised, bug fixed in sequential method, additional tests. Point API completely revised, additional tests and documentation (renamed to Pnt2d).

  • [2020/12/20] Release 1.7. Revised line classes and additional tests. Revised HoughOverlay. New simplified mechanism for accessing Java resources. Setup for JUnit4 testing. Additions to Matrix class (static methods). Revised ConvexHull and AxisAlignedBoundingBox. Revised corner detection, added Shi-Tomasi and MOPS score functions and subpixel-positioning. Added CustomOverlay to imagingbook.lib.ij for easier handling of specific overlay construction (initially used for corner and SIFT detection). Various additions to Arithmetic and Matrix classes. Adapted binary regions and Fourier descriptors to use the common imagingbook.pub.geometry.basic.Point class. Unified the use of GaussianFilter in various applications. Added ImageGraphics in imagingbook.lib.image, facilitating anti-aliased drawing on images (not possible in vanilla ImageJ).

  • [2020/01/06] Release 1.6: Revised packages delaunay, mappings and fitting in imagingbook.pub.geometry. Added a new interface Point to handle various implementations of 2D points across different packages. Two implementations of the Delaunay triangulation are now available which share the same interface. The new implementation (Guibas-algorithm) is roughly ten times faster. mappings and fitting have been harmonized, constructors unified and simplified. Many other fixes and cosmetic corrections.

  • [2019/12/26] Revised DFT and DCT libraries (packages imagingbook.pub.dft, imagingbook.pub.dct) and associated ImageJ plugins (in imagingbook_plugins_all/Spectral_Techniques). Added fast implementations based on the JTransforms package by Piotr Wendykier. Simplified Maven dependency setup (by automatically copying dependencies to ImageJ's jar folder).

  • [2019/12/22] Submodules with plugins for specific book editions have been frozen and will not be maintained any longer. The complete plugin collection is contained in imagingbook_plugins_all. ZIP-archives of the specific plugin sets are now found in plugins-archive.

  • [2019/01/04] Revised geometric mappings (in package imagingbook.pub.geometry.mappings) and related demo plugins. Image-to-image mappings were moved to the new class ImageMapper, for mappings to handle only geometric aspects.
