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

Description

Different vegetation indices can be used to remove the soil. For the list of indices please visit the FIELDimageR manual at link:

Usage

  fieldMask(mosaic,Red=1,Green=2,Blue=3,RedEdge=NULL,NIR=NULL,mask=NULL,index="HUE",cropValue=0,cropAbove=T, DSMmosaic=NULL, DSMcropAbove=T, DSMcropValue=0, plot=T)

Arguments

mosaic	object of class stack with at least 3 bands.
Red,Green,Blue,RedEdge,NIR	respective position of the band at the original image file.
index	vector with the vegetation indices to be calculated. For the list of indices please visit the FIELDimageR manual at link:
mask	if avaliable the soil will be removed following this mask and not the vegetation index, cropValue and cropAbove must be used.
cropValue	referent value of soil in the image.
cropAbove	if TRUE all values above the cropValue will be accounted to make the mask.
DSMmosaic, DSMcropAbove, DSMcropValue	DSM should be used if the file of height is provided.
plot	if is TRUE the original and crop image will be plotted.
