h1. 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.
