image_create

image_create() can be used to create an <code>Image</code> object with a desired color and size.

Tools for single or batch image manipulation and analysis as
described by Olivoto (2022) <doi:10.1111/2041-210X.13803> that can be
used to quantify plant leaf area, assess disease severity, count
objects, obtain shape measures, object landmarks, and compute
Elliptical Fourier Analysis of the object outline, as described by
Claude (2008) <doi:10.1007/978-0-387-77789-4>. Additionally, the
package includes tools for analyzing grids, which enables high
throughput field phenotyping using RGB imagery captured by unmanned
aerial vehicles.
