makeChipsMultiClass

Deprecated. Use makeChips with mode = "Positive" instead.

Usage

makeChipsMultiClass(
  image,
  mask,
  n_channels = 3,
  size = 256,
  stride_x = 256,
  stride_y = 256,
  outDir,
  useExistingDir = FALSE
)

Arguments

image

SpatRaster object or path to input image.

mask

SpatRaster object or path to single-band mask.

n_channels

Number of channels in the input image. Default is 3.

size

Size of image chips in pixels. Default is 256.

stride_x

Stride in the x (columns) direction. Default is 256.

stride_y

Stride in the y (rows) direction. Default is 256.

outDir

Full or relative path to the output directory. You must include the final forward slash (e.g., "C:/data/chips/").

useExistingDir

TRUE or FALSE. Write into an existing directory. Default is FALSE.

Value

Image and mask files written to disk in TIFF format. No R object is returned.

Details

This function is a deprecated wrapper around makeChips. It will be removed in a future version. Replace calls of the form:

makeChipsMultiClass(image, mask, ...)

with:

makeChips(image, mask, ..., mode = "Positive")

Examples

if (FALSE) { # \dontrun{
# Deprecated — use makeChips() instead:
makeChips(image = "INPUT IMAGE NAME AND PATH",
          mask = "INPUT RASTER MASK NAME AND PATH",
          n_channels = 3,
          size = 512,
          stride_x = 512,
          stride_y = 512,
          outDir = "DIRECTORY IN WHICH TO SAVE CHIPS",
          mode = "Positive",
          useExistingDir = FALSE)
} # }
