Changelog SimpleTree 4 - all Beta Versions summary¶

Changelog:

• Beta_32 to Beta_33.06:

• Fixed a bug in DTM
• switched standard allometric correction approach to Xu et al.
• Fixed a bug in statistical outlier filtering
• Lisence added and opening of source code

• Beta_31 to Beta_32:

• Adjustment of steps input and output configuration

• Beta_30 to Beta_31:

• Change in the allometric scaling correction approach

• Beta_28 to Beta_30:

• Change in the parameter optimization

• Beta_21 to Beta_28:

• Bugfix in Segmentation. Should work better now
• Bugfix in DTM modelling
• Prevented some crashes in filtering where empty clouds were produced.
• Added an exporter for ascii 1 file / scene. You can also export the segmented tree clouds directly in my exporter step.
• Added an exporter for DTM to ply

• Beta_17 to Beta_21:

• Improved the Segmentation runtime. It is down to 2 minutes for some test plots.
• Added a SimpleTree DTM step
• Improved few Dialogs
• Added a low quality option for the segmentation
• Made step optional (Upscaling, if number iteration set to 0)

• Beta_15 to Beta_17:
  my final version of my project pipeline. Final does not mean single steps do not get improved anymore, 2 steps even might still be replaced. Regarding the input and output of the pipeline though nothing changes. Fixed a lot of bug and improved both modelling as well as segmentation. Two more dedicated de-noising steps which had been removed are readded. Take those with care, they are quite untested.
• Beta_14 to Beta_15:
  fixed a bug where cut_height was computed correctly but not used for DBH, height and length computation. All three parameters should now be usable.
• Beta_10 to Beta_14:

• Major fit quality improvement, also improved modelling of young trees.
• No change to the output csv format to be downward compatible regarding further analysis
• Added a few steps to make plot level analysis more comfortable. There is one step included which can get rid of segmented undergrowth for example.
• For users who work on plot level, outputfiles which are created adapt their name from your plot cloud.
• DBH is estimated by DTM, not from cutheight as user input. You do not have to give this value in an input file anymore.

• Beta_07 to Beta_10: added plot level processing tools. Improved fit quality. Fixed a lot of bugs. Added various output options. Video tutorials are contained as well.
• Beta_06 to Beta_07: several minor improvement procedures included and minor bug fixes implemented. Changed the user documentation also slightly.
• Beta_05 to Beta_06: added a lot of point cloud steps like de-noising. Fixed minor bugs and updated complete user documentation
• Beta_04 to Beta_05: improved the fit quality for all modellings.
• added test data

• Todo: output, input, tutorials, acknowledgements, release. std out filter should be multithreaded. transfer step for segmentation.
