ergas_spec: ERGAS Spectral Quality index

In pacoalonso/fusionImage: This package implemente three image fusion algorithms (High Pass Filter, Principal Component Analysis, and Gram-Schmidt), and ERGAS fussion quality index

Description

ERGAS Spectral Quality index

Usage

ergas_spec(
  original,
  modified,
  pan,
  method,
  rp = mean(res(pan)),
  rms = mean(res(original))
)

Arguments

original	Raster brick object with the original multispectral bands
modified	Raster brick object with the bands obtained by the fusion process
pan	Raster object with the panchromatic band.
method	Resampling method, should be ‘"bilinear"’ for bilinear interpolation, or ‘"ngb"’
rp	Resolution of the original panchromatic band
rms	Resolution of the original multispectral bands

Value

Quality index

Examples

pca <- pca_fusion(mis=mis, pan=pan, method="bilinear", bits=16)
ergas_spec(original=mis, modified=pca, pan=pan, method="bilinear")
