foto_batch | R Documentation |
This routine process images as a batch, normalizing the PCA analysis across images. This global normalization makes it possible to compare the resulting PCA scores across images and infer trends over different remote sensing tiles or across time.
foto_batch(path, window_size = 61, method = "zones", cores = 1)
path |
directory containing (only) image files to process |
window_size |
a moving window size in pixels (default = 61 pixels) |
method |
zones (for discrete zones) or mw for a moving window approach |
cores |
number of cores to use in parallel calculations |
returns a radial spectrum for a moving window across a raster layer
