roi_check: Show pixel intensities
In colocr: Conduct Co-Localization Analysis of Fluorescence Microscopy Images

Description Usage Arguments Details Examples

Show the pixel intensities of certain image channels

1	roi_check(img, ind = c(1, 2))

`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.

Calling this function returns two plots. The first is a scatter plot of the pixel intensities from two channels. The second is the density distribution of the intensities from the two channels.

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

# choose ROI and show the pixel intensities
oldpar <- par()
par(mfrow = c(1, 2))

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

par(oldpar)
