fieldCrop: Selecting experimental field from original image

In OpenDroneMap/FIELDimageR: A Tool to Analyze Orthomosaic Images From Agricultural Field Trials

Selecting experimental field from original image

Description

It calculates the percentage of object area in the entire mosaic or per plot using the fieldShape file.

Usage

fieldCrop(
  mosaic,
  fieldShape = NULL,
  nPoint = 4,
  plot = TRUE,
  remove = FALSE,
  type = "l",
  lty = 2,
  lwd = 3,
  fast.plot = FALSE
)

Arguments

mosaic	object mask of class stack from the function fieldMask.
fieldShape	crop the image using the fieldShape as reference. If fieldShape=NULL, four points should be selected directly on the original image to determine the experimental field.
nPoint	number of points necessary to select field boundaries or area to remove (4 >= nPoint <= 50).
plot	if TRUE (by default) plots the original and cropped image.
remove	if TRUE the selected area will be removed from the image.
type	character indicating the type of plotting, please check help("lines").
lty	line types, please check help("lines").
lwd	line width, please check help("lines").
fast.plot	if TRUE only the grey scale image will be plotted as reference (faster approach). if TRUE only the grey scale image will be plotted as reference (faster approach).
