[tesseract-ocr] coordinates of a skewed image

Hi,I have given a skewed image as input to Tesseract-ocr. The plain text output generated de-skews the image and is giving the correct output. But in hocr output, the bounding box coordinates of the words are with respect to the original skewed image. So,Is there any way to get the coordinates

The command was the following: tesseract -l eng --oem 1 --psm 0 a.jpg stdout As far as where it occurred exactly, I can't tell. I have been able to reproduce this with multiple jpgs - let me know if you need any further info tesseract --version shows tesseract 4.00.00alpha leptonica-1.74.1

Re: [tesseract-ocr] Train Tesseract 4.0 LSTM based on images

Lstm training is not like legacy training. Please read the wiki pages regarding 4.0 training. I have given all sample commands there. There are 3 different ways of training. Read the bash scripts regarding training to know more. tesstrain.sh with --linedata-only creates the box tiff pairs but

Re: [tesseract-ocr] Train Tesseract 4.0 LSTM based on images

Arabic was never trained with the legacy tesseract engine and I doubt you will get any improvement over existing traineddata using cube or lstm. You are free to experiment and see what you come up with. I have pointed to the bash scripts for training. Please refer to them for the correct

Re: [tesseract-ocr] Re: Tesseract (4 alpha ) Amibiguos Situation while Correcting Chars in box file

You can use jtessboxeditor to edit the box files. Make sure to mark EOL if you are trying to train using scanned images. Also note that this part of code is untested - training 4.0 using pre-existing images and box files. Ray has only explained method for using images created by text2image.
