Hello community,

I have been working on extracting text from images, specifically focusing on seven-segment fonts,
using .NET. Unfortunately, my attempts with popular libraries like Tesseract and IronOcr have been
unsuccessful, as they seem to excel with normal English fonts.

Here's a brief overview of my approach so far:
1. Tesseract: Limited to normal English fonts, unable to recognize seven-segment characters.
2. IronOcr: Similar limitations, not suitable for seven-segment fonts.

Despite these efforts, I'm facing challenges in accurately extracting text from images with
seven-segment fonts.

What I have tried:

Additionally, I've experimented with image processing techniques, including:
• Cropping and zooming to the text region.
• Applying gray, black and white, and binarization filters.

Machine learning / pattern recognition. You feed it the font with the "answers" (a training set; a "subset" of the sample set). Then run tests with the whole sample set.
