Releases

This page records pyTheia releases. It no longer mirrors the historical TheiaSfM upstream changelog; older version notes referred to upstream tarballs and features that this fork no longer ships.

0.6.0

Major cleanup: smaller surface area, Python-first imaging and features, fewer vendored or optional dependencies in the default build path.

Removed or deprecated in this line

  • Raster / EXIF in C++: The theia/image stack and OpenImageIO integration are gone. Images and EXIF are expected in Python (OpenCV, Pillow, etc.). C++ keeps geometry, reconstructions, cameras, BA, and solvers.
  • Feature and descriptor I/O: Reading/writing bundled keypoint–descriptor files and SIFT key formats has been removed from the library and from Python bindings. Feature detection and matching stay outside the core package; you pass correspondences and use Feature, FeatureCorrespondence, and estimators as needed.
  • Python API trim: Descriptor-centric matching helpers (e.g. KeypointsAndDescriptors, brute-force / cascade hash matchers, Fisher-vector globals, two-view verification types that depended on that stack) are no longer exposed on pytheia.matching / pytheia.sfm. FeaturesAndMatchesDatabase, InMemoryFeaturesAndMatchesDatabase, ReconstructionBuilder, and ReconstructionBuilderOptions are also removed from Python (C++ Theia still uses the match database inside its own reconstruction-builder path).
  • Exports and extras: Legacy PMVS export and other dead or redundant tooling paths have been removed or stripped from docs and CMake where applicable.
  • Documentation: Sphinx-era pages were replaced with MkDocs; narrative docs focus on what pyTheia actually exposes and how to wire Python-side features into SfM.

Still here

  • Core SfM pipelines, bundle adjustment, cameras, pose / triangulation solvers, view graph, I/O for reconstructions (binary/JSON, Bundler, NVM, COLMAP text, PLY, Nerfstudio, SDFStudio, etc.), and pybind11 Python API for the remaining types and functions.
