Sending Batch request to azure cognitive API for TEXT-OCR

Inizia esaminando l’endpoint Azure Cognitive API utilizzato in recognise_text, in particolare la richiesta recognizeText e il relativo flusso di polling di Operation-Location. L’issue non indica alcun file o test del repository, e il completamento non è definito perché chiede se sia possibile inviare più immagini in un’unica richiesta.

I am calling azure cognitive API for OCR text-recognization and I am passing 10-images at the same time simultaneously (as the code below only accepts one image at a time-- that is 10-independent requests in parallel) which is not efficient to me, from processing point of view, as I need to use extra modules i.e: Celery and multiprocessing.

So, is there a way to send all the 10-images in a single request and get the output at once then do post processing?

import time
from io import BytesIO

import cv2
import requests
from PIL import Image as PILImage
from PIL import Image
file_list = []

headers = {
    "Ocp-Apim-Subscription-Key": "<API-KEY>",
    'Content-Type': 'application/octet-stream'}

p = "symbol_sample.jpg"
print(p,"p")

def recognise_text(p):
    p = cv2.imread(p)
    cropped_image = PILImage.fromarray(p)
    buffer = BytesIO()
    cropped_image.save(buffer, format="JPEG")
    image_bytes = buffer.getvalue()
    try:
        response = requests.post(
            "https://centralindia.api.cognitive.microsoft.com/vision/v2.0/recognizeText?mode=Printed",
            headers=headers,
            data=image_bytes
        )
        header_link = str(response.headers['Operation-Location'])
        while (True):
            headers_get = {
                "Ocp-Apim-Subscription-Key": "<API-KEY>"",
                'Content-Type': 'application/json'
            }
            result = requests.get(
                url=header_link,
                headers=headers_get
            )
            response_r = result.json()
            if response_r["status"] == "Succeeded":
                return response_r
            else:
                time.sleep(4)
    except Exception as e:
        print(e)
        return ""
    
image1="symbol_sample.jpg"
o = recognise_text(image1)
print(o)

Any help would be really appreciated.
