Timeline

Below is a simplified timeline of DICOMautomaton development, broken down by month.

202010

  • Reworked EQDx operation to also provide BED conversion, added tests.
  • Simplified very old code (contours_with_meta class).
  • Simplified ROI operation parameter selectors and documentation.
  • Webserver: relocate config directory, simplify parameter selection when exmaples are exhaustive.
  • Add SDL2 and Glew dependencies on all platforms.
  • SFML_Viewer: provide cross-platform partial replacements for Zenity dialogs.
  • Explicator: provide built-in lexicon, default to most generic lexicon provided by Explicator (if available).
  • ContourSimilarity: sync documentation with current implementation.
  • Documentation: indicate version in online documentation.
  • Added mock-up starting point for deformable registration algorithm development.

202009

  • Added development log.
  • Modernized use of 'new' for Contour_Data and Image_Data unique_ptr/shared_ptr allocations.
  • Added support for nested operations and meta-operations, Repeat and ForEachDistinct. These can be used to partition data, analyze group-wise, or implement control flow at the level of operations.
  • Nix: nix files reconfigured to use git master branches rather than commit pinning.

202008

  • Successfully ported DCMA to Windows.
  • CI: added MXE cross compilation and expose build artifacts.
  • CI: expanded number of builds and test matrix, added nightly scheduled builds.

202007

  • CI: updateCI scripts and AppImage creation, switched base image to Debian for greater stability.
  • Docker: separated setup scripts from Dockerfiles for easier re-use.
  • Docker: parameterized multi-part builds.
  • Addressed some static analysis warnings (memcpy, localtime, if(false), std::bind, ...).
  • CI: publish AppImage artifacts.
  • CMake: better support for ARM builds.

202006

  • ReduceNeighbourhood: support statistical standarization.
  • ReduceNeighbourhood: support adaptive renormalization.
  • CMake: easier support for sanitizer builds.
  • TPS-RPM: report bending energy, support for alternative solver methods, support double-sided outlier handling, added tolerance-based Sinkhorn normalization for adaptive refinement, finalize user-interface.
  • IO: normalize floating-point precision to maximum for exact round-trips.
  • AnalyzeHistograms: fix conversion typo (cm^3^ to mm^3^).
  • Added Transform3 as first-class object to support registrations.

202005

  • Preliminary TPS-RPM implementation for deformable registration.
  • Many small tweaks throughout code base (UID generation, debugging features, IO
  • Added test files for meshing.
  • Simple_Meshing: force manifoldness at edges.
  • Added Simple_Meshing routine to quickly stitch together well-behaved contours. It is experimental, but has limited support for N-to-M contour connections, holes, and nested contours. Meshes produced this way are extremely unreliable, except in well-constrained situations!
  • Support for explicit DVH Line_Sample files.

  • File_Loader: support (uncompressed) TAR files.
  • DICOMExportImagesAsCT: upstream class name change.
  • Support writing TAR archives when exporting multiple files (e.g., CT images).

  • Upstream (Ygor) planar_image_adjacency change: switched from map to linear lookups for int-to-images, which will significantly speed-up ray-casting through rectilinearly voxelized geometries.
  • Added basic treatment plan analysis routine. Basically just a shell to build on later (e.g., for automated plan checks).
