There are many ways to use this tool.

(a) if you have Matlab (may require newer version and certain toolboxes) installed:

Option 1. Call the entry level funtion "PlantMove_matlab.m" as:

motionfield = PlantMove_matlab(X,Y,denoise,dsp,k,plotflag);

%% motionfield = PlantMove_matlab(X,Y,denoise,dsp,k)
%
%  Matlab function to estimate 3D motion field between two point clouds
%  (i.e., how X is transformed to Y)
%
%  Inputs:
%  X & Y: nx3 point clouds;
%
%  (Optional) denoise: knn neighbor size to denoise point clouds. Default
%  value is 4. If no denoise is to be performed, specify it to 0;
%
%  (Optional) dsp: Voxelsize [dsp*average spacing] to uniformly downsample
%  point clouds. Default value is 3. If no downsampling is to be performed,
%  specify it to 0;
%
%  (Optional) k: factor [k*average spacing] controls the starting Voxelsize
%  in progressive registration. This factor is a tradeoff beteen speed and
%  accuracy. Default value is 20. Specify it to 0 to automatically estimate
%  a k value;
%
%  (Optional) plotflag: plot results (1) or not (0).
%
%  Output:
%  motionfield: nx6 matrix with a nx3 point cloud and a nx3 motion field.


Option 2. Drag "PlantMove.mlappinstall" into Matlab workspace. This will install a Matlab App for you.


(b) if you don't have Matlab installed, and don't want to install it:
Run "PlantMove_installer.exe" for win64. If you need an excutable for other systems (Linux and Mac), please contact me.
(PS: Matlab Runtime 2021b (freely available at https://se.mathworks.com/products/compiler/matlab-runtime.html) is required. You can either install it in advance or do it during the installation of PlantMove.)

--------------------------
*Note that if you load an ascii point cloud with the interface, only space delimiter is supported (without header). Currently, these formats are supported: .las; .mat; .xyz; .txt; .ply; .pcd (recommend to use more generic formats for point clouds, such as las, ply, and pcd)
