Re: [tesseract-ocr] Tesseract 4.0 doesn't see the changes after Arabic traning

Arabic traineddata for 3.0x uses cube engine. Training process for that was never shared. Now the cube engine has been removed for lstm 4.0, which is still in alpha stage. There is 4.0alpha traineddata for Arabic and you can train for it , but accuracy is not great. Ray is doing another training

Have you tried just using the eng.traineddata directly with tess 3.04/ 3.05 / 4.0? You don't need to train unless it is a very special case. You can try changing the dictionary dawg files with tess 3.0x. ShreeDevi भजन - कीर्तन -

Saurabh, It depends on what you want to do with the bash script. Here is a sample of a script I used to compare results using diff tessdata files by looping thru a set of image files. Google the bash commands to figure out what they do! #!/bin/bash set -vx export
