About
The code serves the API for OCR.
The program accepts two endpoints: image-sync and image.
Synchronous inference
The image-sync ednpoint receives base64 images
curl -POST "http://localhost:5000/image-sync" -d '{"image_data": "<b64 encoded image>"}'
and return a json response
{
"text": "<recognized text>"
}
Asynchronous inference
The image ednpoint receives base64 images for POST requests
curl -POST "http://localhost:5000/image" -d '{"image_data": "<b64 encoded image>"}'
and return a json response
{
"task_id": "<task id>"
}
After that, the results of the inference can be retrieved with GET request on the image ednpoint
curl -GET "http://localhost:5000/image" -d '{"task_id": "<task id>"}'
and return a json response if the inference is done
{
"task_id": "<recognized text>"
}
otherwise, return None
{
"task_id": null
}
