Collections-OCR
A script to batch collections label-images through OCR
Dependencies
Make sure to install these libraries first:
magick
- to read in image filestesseract
- to do OCR magicstringr
- to split the OCR'ed lines to columns
How to run the script:
Notes:
- This can takes over 10 seconds per label-image.
- Be mindful how many images you add to your "images" directory.
- This currently uses Tesseract's English ("eng"), German ("deu"), and Latin ("lat") libraries.
- Output likely needs some [or many] follow-up/clean-up steps.
- Batch similar images together to streamline follow-up steps.
To run the script:
- Add a folder named "images" to this script's directory
- Add the images (JPG & JPEG) you'd like to OCR to that directory
- Run the script (
Rscript ocrMangle.R
)
Output
A CSV named "ocrText-[Date-time].csv", containing these columns:
- "image" = filename for each JPG and JPEG
- "line_count" = number of lines in each OCR transcription
- "Line1" - "Line[N]" = text for each line in the OCR transcription.
- the number of "Line" columns will match the maximum number of lines as needed.
