ggmorph_tile: Tile morphs within a morphological space

In jiho/morphr: Analyse the Morphology of Objects on Images

Tile morphs within a morphological space

Description

Tile morphs within a morphological space

Usage

ggmorph_tile(
  space,
  imgs,
  dimensions = c(1, 2),
  steps = 5,
  n_imgs = 5,
  adjust_grey = TRUE,
  scale = 0.01,
  fun = NULL,
  ...
)

Arguments

space	morphological space object created by morphospace().
imgs	vector of paths to images; should have as many elements as are in the morphological space
dimensions	couple of dimensions to plot.
steps	number of steps along each dimension that define the tiles.
n_imgs	number of images to randomly select and morph in each tile.
adjust_grey	whether to adjust the mean grey level of the morphed image to match that of the original images it was constructed with. Usually, computing the average (i.e. the morphing) results in lighter images; this compensates it a little. Note that it requires more intense computation and is therefore switched off by default.
scale	scaling factor used to display the images; from pixels to morphological space dimensions units.
fun	function to apply to each image, as a pre-processing step (a typical one is img_chop() to remove a scale bar added to the image).
...	passed to fun.

Examples

space <- morphospace(plank[,-(1:2)], weights=plank$conc)
img_root <- system.file("extdata", "plank", package="morphr")
imgs <- file.path(img_root, paste0(plank$id, ".jpg"))
ggmorph_tile(space, imgs, fun=img_chop, bottom=10)
ggmorph_tile(space, imgs, step=8, scale=0.005)
ggmorph_tile(space, imgs, dim=c(3,4), scale=0.004)
