Spammers are starting to put "speckles" in their images to defeat OCR-scanning plugins such as FuzzyOCR.
I thought ImageMagick's -despeckle option would help, but it doesn't seem to, not even when applied multiple times, not even in conjunction with -monochrome. I want a filter that does this for each pixel X: 1) if any of X's 8 neighbor pixels is the same color, turn X black 2) otherwise, turn X white Can some combination of options to convert do this? I realize that: 1. This will only work w/ indexed-color images (eg, GIFs) and not JPEGs, etc. 2. Spammers will soon work around this, so this is just a short-term bandage. 3. I could write something in libgd to do this (blech!) -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology. We feel that resistance to new ideas and technology is unwise and ultimately futile.
