Jupyter Notebook with Python samples for the Cognitive Services Computer Vision API

Azure Computer Vision API: Jupyter Notebook

This Jupyter Notebook demonstrates how to use Python with the Azure Computer Vision API, a service within Azure Cognitive Services.

If you have the Jupyter Notebook application, clone this repository to your machine and open the .ipynb notebook files located in the Jupyter Notebook folder. If you want to try the notebooks on the web, you can use Binder by following these links:

• Computer Vision API example
• Handwriting OCR API example

Next steps

• Learn about the Computer Vision API
• Read the documentation

cognitive-vision-python's Issues

Cell 1 - commands in wrong order

from future import print_function
needs to be moved to the top. Otherwise gets errors!

Error code: 404

I followed your tutorial but when I tried to insert in my own image it come out as follow

below are my codes:

and here is my variables:

I took my URL and key from cognitive services

No OpenCV library in binder.org

When I open this notebook in mybinder.org using the link on the ReadMe page: https://mybinder.org/v2/gh/microsoft/Cognitive-Vision-Python/master?filepath=Jupyter%20Notebook/Handwriting%20OCR%20API%20Example.ipynb

It gets an error when I run the first set of python statements saying that it can't find the opencv library.

Notebooks corrupt?

I'm having trouble viewing these notebooks on Github. Downloading the repository and trying to open the notebooks locally is returning the following error:

Unreadable Notebook: Y:\pdata\174741\Project Info\Python_Scripts\misc\Cognitive-Vision-Python-master\Cognitive-Vision-Python-master\Jupyter Notebook\Computer Vision API Example.ipynb NotJSONError('Notebook does not appear to be JSON: '{\n "cells": [\n {\n "cell_type": "m...')

jupyter notebook files are corrupt

Hi Team ,
can you please upload fresh jupyter notebook files as existing files are not opening . it would be great help . thanks in advance

Tiff Images and PDF

Was wondering if I can use the same model for PDF's and TIFF images that have handwritten text on the document similar to the below implementation

Error Code 200

I got an Error Code 200 and I don't know how to fix it

TypeError: post() takes from 1 to 3 positional arguments but 5 were given

Description

Hi, a colleague and I have been working on a script that extracts text from image files (.png)

For that he (colleague) has been using the method computervision_client.recognize_printed_text_in_stream().

Since last Thursday, Feb-25-2021, this method stopped working properly.

When called, it generates the following error:

TypeError Traceback (most recent call last)
in
----> 1 ocr_result_local = computervision_client.recognize_printed_text_in_stream(image=open(contrato, "rb" ))

/anaconda/envs/azureml_py36/lib/python3.6/site-packages/azure/cognitiveservices/vision/computervision/operations/_computer_vision_client_operations.py in recognize_printed_text_in_stream(self, image, detect_orientation, language, custom_headers, raw, callback, **operation_config)
1406
1407 # Construct and send request
-> 1408 request = self._client.post(url, query_parameters, header_parameters, body_content)
1409 response = self._client.send(request, stream=False, **operation_config)
1410

TypeError: post() takes from 1 to 3 positional arguments but 5 were given

In which platform does it happen?

Azure Machine Learning Studio

How do we replicate the issue?

Just try to use the module: computervision_client.recognize_printed_text_in_stream()

Expected behavior (i.e. solution)

It should extract text from an image file.

Other Comments

I saw that something similar occurred here: microsoft/botbuilder-python#93

Error code: 400

Last cell: Analysis of an image retrieved via URL
Error code: 400
Message: {u'error': {u'message': u'Failed to download image.', u'code': u'FailedToDownloadImage'}}

Error Code 401

Hi,
I changed the Api URL and prediction key but still getting this issue after resolving bugs.

Thanks in advance

Realtime video example in Python?

A C# Example for using Cognitive Vision on Real time videos can be found here. https://docs.microsoft.com/en-us/azure/cognitive-services/computer-vision/vision-api-how-to-topics/howtoanalyzevideo_vision

I cannot find something similar for Python.
How would I go about do that in Python?

Printed vs Handwritten detection

I have successfully used the code here to recognise Handwritten text. However, how do I use it to detect Printed text? The goals is to separate printed and handwritten text in an image where both printed and handwritten texts are present.

Either params = {'mode' : 'Printed'} or params = {'mode' : 'Handwritten'} detects both printed and handwritten text.

Complete Client Library in Python?

I was wondering whether we could have a client library in Python that is more in sync with the windows client for the service.

I could contribute something I wrote while working on a project recently.

Repo description incorrectly states this is "Python SDK for MS Computer Vision SDK"

The description for this repository incorrectly states that it is the Python SDK for the Computer Vision API, when in fact it is a Jupyter notebook containing samples for the Python SDK.

The incorrect description causes SEO to rank it higher than the real GitHub repository containing the SDK:

Please update the description for this repository to more accurately reflect its contents, such that it doesn't compete with the SDK repository. Something like:

Sample Jupyter notebook for Azure Cognitive Services Computer Vision

Wrong value for _url

It should be this:
_url = 'https://api.projectoxford.ai/vision/v1.0/analyze'

instead of:
_url = 'https://api.projectoxford.ai/vision/v1/analyze'
