`img`	A `cimg` object or a `list` of multiple images such as the one returned from `roi_select`
`ind`	A `numeric` object of length two. For the channel indexes. or a `list` of similar vectors for each of `img` items.

# load images
fl <- system.file('extdata', 'Image0001_.jpg', package = 'colocr')
img <- image_load(fl)

# choose and show ROI
oldpar <- par()
par(mfrow=c(2,2))

roi_select(img, threshold = 90) %>%
  roi_show()

par(oldpar)
