recolorize (version 0.2.0)

splitByColor: Split color clusters in a recolorize object into layers

Description

Separates color clusters from a recolorize(), recluster(), or imposeColors() object into binary masks.

Usage

splitByColor(
  recolorize_obj,
  layers = "all",
  plot_method = c("overlay", "binary", "colormask", "none")
)

Value

A list of binary matrices (1/white = color presence, 0/black = color absence), one per color center.

Arguments

recolorize_obj

A recolorize object from recolorize(), recluster(), or imposeColors().

layers

Either "all" or a numeric vector of which color centers to return.

plot_method

Plotting method for plotting the color layers. Options are"overlay", "binary", "colormask", or "none".

Examples

# get original fit
corbetti <- system.file("extdata/corbetti.png", package = "recolorize")
recolored_corbetti <- recolorize::recolorize(corbetti, plotting = TRUE)

# to reset graphical parameters:
current_par <- graphics::par(no.readonly = TRUE)

# make a layout
layout(matrix(c(1, 1:9), nrow = 2))
par(mar = c(0, 0, 2, 0))
# plot original
plotImageArray(recolored_corbetti$original_img)

# plot layers
corbetti_layers <- splitByColor(recolored_corbetti, plot_method = "over")

# plot binary maps
plotImageArray(recolored_corbetti$original_img)
for (i in 1:length(corbetti_layers)) {
  plotImageArray(corbetti_layers[[i]])
}
