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."
