R Documentation

Stack-thresholded image class.

A stack-thresholded array is an array which has had stack-thresholding applied to it. See mean_stack_thresh(). It has 3 necessary attributes:

thresh is the threshold that was applied. This is either a number or an object of class th. Values in the original array which were less than this value are deemed to have failed the thresholding.
fail_value is the value to which elements of the array which failed the thresholding were set. This could be something like 0 or NA.
stack_thresh_method details which stacked-thresholding method was employed; this is either "mean" or "median".

stack_threshed_img(img, thresh, fail_value, stack_thresh_method)

`img`	A 4-dimensional array in the style of an ijtiff_img (indexed by `img[y, x, channel, frame]`) or a 3-dimensional array which is a single channel of an ijtiff_img (indexed by `img[y, x, frame]`).
`thresh`	The threshold that was used. Either a number or an object of class th.
`fail_value`	The value to which elements of the array which failed the thresholding were set.
`stack_thresh_method`	This must be set to either `"mean"` or `"median"` to tell which stacked-thresholding method was employed.

An object of class stack_threshed_img.
