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)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]).
The threshold that was used. Either a number or an object of class th.
The value to which elements of the array which failed the thresholding were set.
This must be set to either "mean" or "median"
to tell which stacked-thresholding method was employed.
An object of class stack_threshed_img.
