transform: Make a Transform

In facelab/webmorph: Reproducible Stimuli

Description

The first 7 arguments are vectorised, so you can put in a vector of image names or shape/color/texture values.

Usage

transform(
  trans_img = NULL,
  from_img = NULL,
  to_img = NULL,
  shape = 0,
  color = 0,
  texture = 0,
  outname = NULL,
  norm = c("none", "twopoint", "rigid"),
  normpoint = 0:1,
  sample_contours = TRUE,
  warp = c("multiscale", "linear", "multiscalerb"),
  format = c("jpg", "png", "gif")
)

Arguments

trans_img	image(s) to transform
from_img	negative end of the transform dimension
to_img	positive end of the transform dimension
shape, color, texture	amount to transform (1.0 = 100% of the difference between the from_img and to_img)
outname	local path to save transform to
norm	how to normalise
normpoint	points for twopoint normalisation
sample_contours	whether to sample contours
warp	warping algorithm to use
format	image format

Value

stimlist

Examples

## Not run: 
  stimuli <- demo_stim()
  transf <- transform(
    trans_img = stimuli, # transform all stimuli
    from_img = stimuli$f_multi,
    to_img = stimuli$m_multi,
    shape = c(fem = -0.5, masc = 0.5)
  )
  plot(transf, nrow = 2, labels = TRUE)

## End(Not run)
