mosaic_chm_extract

This function extracts height-related summary statistics from a CHM using a
given shapefile.

Tools for both single and batch image manipulation and
analysis (Olivoto, 2022 <doi:10.1111/2041-210X.13803>) and
phytopathometry (Olivoto et al., 2022 <doi:10.1007/S40858-021-00487-5>).
The tools can be used for the quantification of leaf area, object
counting, extraction of image indexes, shape measurement, object
landmark identification, and Elliptical Fourier Analysis of object
outlines (Claude (2008) <doi:10.1007/978-0-387-77789-4>). The package
also provides a comprehensive pipeline for generating shapefiles with
complex layouts and supports high-throughput phenotyping of RGB,
multispectral, and hyperspectral orthomosaics. This functionality
facilitates field phenotyping using UAV- or satellite-based imagery.
