fieldMask: Removing background (e.g., soil) using vegetation index.

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

Removing background (e.g., soil) using vegetation index.

Description

A fct function

Different vegetation indices can be used to remove images background. For the list of indices please visit the FIELDimageR manual at link: https://github.com/OpenDroneMap/FIELDimageR#P6

Usage

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

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.
mask	if avaliable the soil will be removed following this mask and not the vegetation index, cropValue and cropAbove must be used.
index	vector with the vegetation indices to be calculated. For the list of indices please visit the FIELDimageR manual at link:
myIndex	user can calculate a diferent index using the bands names, e.g. "(Green+Blue)/Red-NIR/RedEdge"
cropValue	referent value of soil in the image.
cropAbove	if TRUE all values above the cropValue will be accounted to make the mask.
projection	if TRUE the projection will not be accounted to 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.

Value

The return value, if any, from executing the function.

A list with elements:

• The function returns a image format stack with the original bands (layers) without the background and mask with logical values of 0 and 1 for vegetation or soil.
