Maybe it would be better to start a new thread for this question, but anyway, here goes.
1. Search for any directory
2. If directory contains any non-dot files, skip it (= mark for keeping).
3. Otherwise, print it.
Maybe radoulov can come up with an elegant one-liner for this; it's not particularly succinct.
This just echoes the directories; if it seems to work for you, you can change the echo to rm -rf
If your shell doesn't expand non-matching wildcards to an empty string, you might need the case which I commented out, too. (Actually maybe the .* case is redundant; wildcards don't expand dotfiles in bash at least.)

EMPTY-PAGE(1) ExactImage Manual EMPTY-PAGE(1)NAME
empty-page - empty page detector of the ExactImage toolkit
SYNOPSIS
empty-page [option...] {-i | --input} input-file
empty-page {-h | --help}
DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
depths natively, resulting in low memory and computational requirements.
empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can
be removed from the image processing stream.
OPTIONS -i file, --input file
Read image from the specified file.
-m n, --margin n
Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16.
-p x, --percentage x
Set fraction of permissible dark pixels. The default is 0.05 (5%).
-h, --help
Display help text and exit.
EXAMPLES
$ empty-page -i test.tif
The image has 75461 dark pixels from a total of 1060992 (7.11231%).
non-empty
EXIT STATUS
The exit status is 0 if the image is mostly white, 1 otherwise.
