[Web4lib] graphics based content filter

[Andrew Mutch]

John,

There are filters that purport to block images based on flesh tones, etc.
Here's one example (just what I found via Google):

http://www.ltutech.com/en/technology-and-products.image-filter.html

All of the reviews I've read of these products is that they seriously
overblock. This particular product claims it blocks 96% of pornographic
images. What they don't tell you is how many non-pornographic images are
blocked as well. Unfortunately, it appears that these filters don't "know
it when they see it".
