Detecting Nude Pictures in WPMU-Blogs?

Hello,

what do you do on Edublogs against Nude pictures and/or more explicit content?

I know there are scripts available which can detect an unusal high amount of skin (and still sort out faces).

Many thanks…

Regards Bernd

    HI Tom,

    thanks for the fast response. What I need is a “plugin” which informs me of such incidents. I want to build a website in which they can sjowcase there work, but nude only in private and password protected Galleries.

    Here is a Javascript example: http://www.patrick-wied.at/static/nudejs/. He handles also detection of faces…. (but I don’t want to handle that on the Client).

    Here is some Phyton-code I found on the web, but never tried it :slight_smile: They classify Porn as a Skinrate over 30% (but no Face-Portrait-Detection)

    #!python

    import os, glob

    from PIL import Image

    def get_skin_ratio(im):

    im = im.crop((int(im.size[0]*0.2), int(im.size[1]*0.2), im.size[0]-int(im.size[0]*0.2), im.size[1]-int(im.size[1]*0.2)))

    skin = sum([count for count, rgb in im.getcolors(im.size[0]*im.size[1]) if rgb[0]>60 and rgb[1]<(rgb[0]*0.85) and rgb[2]<(rgb[0]*0.7) and rgb[1]>(rgb[0]*0.4) and rgb[2]>(rgb[0]*0.2)])

    return float(skin)/float(im.size[0]*im.size[1])

    for image_dir in (‘porn’,’clean’:wink::

    for image_file in glob.glob(os.path.join(image_dir,”*.jpg”:wink:):

    skin_percent = get_skin_ratio(Image.open(image_file)) * 100

    if skin_percent>30:

    print “PORN {0} has {1:.0f}% skin”.format(image_file, skin_percent)

    else:

    print “CLEAN {0} has {1:.0f}% skin”.format(image_file, skin_percent)

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
