|
|
|
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.
