问题 I am using this article to solve captchas. It works by removing the background from the image using AForge, and then applying Tesseract OCR to the resulting cleaned image. The problem is, it currently relies on the letters being black, and since each captcha has a different text color, I need to either pass the color to the image cleaner, or change the color of the letters to black.

Assuming I stripped the title/author info from the image and filename, would that be enough? Would the fact that it was a unique system on a fairly small website be enough to make it effective? Just how tricky are the spam bots
