I’m building an automated form-submission workflow and need a C# component that reliably deciphers text-based CAPTCHAs that use custom fonts. The images are not wildly distorted, but the lettering differs from standard OCR sets, so off-the-shelf libraries struggle.
Here’s what I’m after: a reusable class or small DLL that accepts a bitmap/byte array of the CAPTCHA and returns the decoded string quickly enough for live form submissions. You’re free to use Tesseract, IronOCR, Emgu CV, or a lightweight CNN you train yourself—as long as the final code runs under .NET 6, compiles cleanly, and requires no paid dependencies.
Please include a minimal console project that demonstrates the call pattern and shows typical accuracy on a handful of sample images I’ll supply. If you train a model, ship the trained weights alongside the code so I can retrain later if the provider tweaks the font. Target accuracy is 90 %+ on the sample set; feel free to suggest preprocessing tricks to get there.
Once delivered I’ll drop the reader into my service and test against live traffic, so clarity, clean error handling, and straightforward licensing are a must.
