Read tables with OpenCV & Tesseract OCR
$30-250 USD
Płatność przy odbiorze
Project Mission:
Convert images of tables to CSV-formatted tables.
Requirements:
OpenCV (Python or Java)
Tesseract v4
Docker
A set images of tables will be provided. It's important not to optimize the solution for these specific tables. The solution must be generic and will be tested against other images of tables.
It is a priority to handle regular tables with high precision. Pie-charts and similar diagrams are a bonus.
Proposed steps:
1. Analyze images using OpenCV to determine table cells (rows and columns).
2. Slice input image into multiple images based on cells.
2. Use Tesseract 4 to OCR text from each cell.
4. Output data to CSV
Expected outcome:
- Conversion is at least 95% accurate with our test-set. Standard tables but not provided to avoid overfitting.
- Docker image with all dependencies provided.
- Function / Script / API that takes an image and outputs CSV-table.
