Description
This package is a helpful wrapper around functions from mainly the Momocs (Bonhomme et al. 2014), EBImage (Pau et al. 2010), and imager (Barthelme et al. 2020) packages. It is designed for the fast and easy extraction of single outline shapes of, for example, stone tools from images containing multiple thereof, such as the ones present in archaeological publications.
This release is provided with a testing dataset, using the Morar Quartz Industry image (Credit: Wellcome Collection, https://wellcomecollection.org/works/th7egtfj, distributed under CC BY 4.0).
A brief explanation of the workflow and the package functions can be found on github.com/yesdavid/outlineR.
