Model OCR Extract Node

This node extracts text from images using an OCR (Optical Character Recognition) model. It takes an image as input and outputs the extracted text as a string.

Examples

Model OCR Extract Node Example

Given the following dataset:

| ImageColumn |
|---|---|
| [image data] |

If you configure the Model OCR Extract node to extract text from the ImageColumn, the output would look like this:

ImageColumn OutputOCRColumn

[image data] “This is the extracted text from the image.”
