v0.3.1

This release has much-improved documentation, added feature extractors with the support of parameterized feature extractors and miscellaneous bugfixes.

v0.3.0

Normalization functionality and faster feature calculations.

v0.2.0

New cell and cube (or voxel) volumes added. Available volumes types are now:

• Infinite cylinder
• Sphere
• Cell
• Cube

Read me now comes with description of test procedure for all features.

laserchicken v0.1.1

Added tests and many bug fixes.
These are mostly fixes for corner cases in feature extractors. For instance some feature extractor used to crash when they were processing a point cloud with zero points. This has been solved for every feature extractor.

laserchicken v0.1.0
