fieldCrop: Selecting experimental field from original image

In angel30mpa/ampa: FIELDimageR: A R Package to Analyze Orthomosaic Images from Agricultural Field Trials

Description

Reduction of the original image size using the experimental field as reference

Usage

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

Arguments

mosaic	object of class stack.
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).
remove	if TRUE the selected area will be removed from the image.
plot	if TRUE (by default) plots the original and cropped 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).

Details

The function returns a new reduced image from experimental field with stack format.

Value

Image format stack.
