Repo:

Provide support for:

• Detection
• Optional: English recognition

Tried detection models from here:
https://github.com/PaddlePaddle/PaddleOCR/blob/develop/doc/doc_en/inference_en.md

• EAST was bad. Don't know why
• Output of DB Detector model:
  

Doesn't detect most Hindi boxes. Was trained only on English data

Further options:

• Train / Fine-tune detector?
  • Use GK's Synthetic data?
• Use recognizer only?
  • No. It's just English only. Too much hassle
