Tesseract Recognition using psm13 for charatcers like "t", "i", "j"

[Purushotham Rao Eravalli]

Hi,

I retrained tesseract with Calibiri, arial. While testing on the cropped text images I am facing issues where the characters "t", "i", "j" are all recognised as "l" adn sometimes "e" as "a". Does someone have solution for this.

Thanks,

Purushotham

Can you provide testing images?

 I do not think there is any need to retrain  tesseract for common font like Arial.

IMO 4.1 should produce the same result. I use model from tessdata_best.
