Collections-OCR

A script to batch collections label-images through OCR

Dependencies - make sure to install these libraries first:

• magick - to read in image files
• tesseract - to do OCR magic
• stringr - to split the OCR'ed lines to columns

Notes:

• this takes ~2 seconds per label-image
• this currently uses Tesseract's English ("eng"), German ("deu") and Latin ("lat") libraries.

To run the script:

1. Add a folder named "images" to this script's directory
2. Add the images (JPG & JPEG) you'd like to OCR to that directory
3. 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.
