%description
Minirhizotrons are widely used to observe and explore roots and their
growth. This package provides the means to stitch images and divide them
into depth layers. Please note that this R package was developed alongside
the following manuscript: Stitching root scans and extracting depth layer
information -- a workflow and practical examples, S. Kersting, L. Knüver,
and M. Fischer. The manuscript is currently in preparation and should be
citet as soon as it is available. This project was supported by the
project ArtIGROW, which is a part of the WIR!-Alliance ArtIFARM –
Artificial Intelligence in Farming funded by the German Federal Ministry
of Research, Technology and Space (No. 03WIR4805).
