Hi Shree, Thank you for quick response. I used the trained data by downloading the datasets at https://github.com/tesseract-ocr/tessdata, https://github.com/tesseract-ocr/tessdata_best and https://github.com/tesseract-ocr/tessdata_fast.
I ran following commands for each of these datasets and changed psm from 1 to 13 , but more or less the output is like the one I posted. Couldn't get the output as you have posted that has data in the right order of the context. tesseract --tessdata-dir tessdata_best-master "sample.tif" sample --psm 1 tesseract --tessdata-dir tessdata_fast-master "sample.tif" sample --psm 1 tesseract --tessdata-dir tessdata-master "sample.tif" sample --psm 1 Not sure what I am doing wrong here, appreciate your help with this.
