You probably want to use label_region.

Yeah, Label_Region in conjunction with the reverse indices output from
Histogram. This would work, assuming you have a procedure DRAWBOX
that draws bounding boxes.
regs = label_region(image)
hist = histogram(regs, reverse_indices = r, min = 1, omax = n_regs)
for i = 0, omax - 1 do begin
coords1d = r[r[i]:r[i+1]-1]
coords2d = array_indices(image, coords1d)
lower_left = min(coords2d, dimension = 2, max = upper_right)
drawbox, lower_left, upper_right
endfor
