Performs PCA for all images and create PCA file with either all or a selection of PCs

perform_PCA(
  input_raster_path,
  output_dir,
  input_rast_wl = NULL,
  input_mask_path = NULL,
  Continuum_Removal = TRUE,
  TypePCA = "SPCA",
  NbPCs_To_Keep = 30,
  Excluded_WL = NULL,
  nbPix_PCA = 1e+06,
  nbIter = 20,
  maxRows = 100,
  filetype = "GTiff"
)

Arguments

input_raster_path: character. path for image to be processed
output_dir: character. Path for output directory
input_rast_wl: numeric. spectral bands corresponding to input_raster_path
input_mask_path: character. path for mask corresponding to the image
Continuum_Removal: boolean. Set to TRUE if continuum removal should be applied
TypePCA: character. Type of PCA: choose either "PCA" or "SPCA"
NbPCs_To_Keep: numeric. number of components to ke saved in the PCA file. default = 30 if set to FALSE (or nb PC if <30)
Excluded_WL: numeric. Water Vapor Absorption domains (in nanometers, min and max WL). Can also be used to exclude spectific domains. dims = N x 2 (N = number of domains to be eliminated)
nbPix_PCA: numeric. number of pixels to use to compute PCA
nbIter: numeric. nb of iterations averaged to compute diversity indices
maxRows: numeric. max number of rows in each block
filetype: character. gdal driver

Value

list of paths corresponding to resulting PCA files
