# 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
|
|
|
|
## How to run the script:
|
|
Notes:
|
|
- This takes ~2 seconds per label-image.
|
|
- Be mindful how many images you add to your "images" directory.
|
|
- Batch similar images together to facilitate the follow-up cleaning.
|
|
- This currently uses Tesseract's English ("eng"), German ("deu"), and Latin ("lat") libraries.
|
|
- Output is likely needs some [or many] follow-up/clean-up steps.
|
|
|
|
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.
