How do I read the seven segment font(OCR)?

Question

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.

Additionally, I've experimented with image processing techniques, including:

• Cropping and zooming to the text region.
• Applying gray, black and white, and binarization filters.
