Creating docker application from local system using Docker CLI

• To create a machine using Docker CLI:
  • docker-machine create --driver azure --azure-subscription-id <subs-id> --azure-location <location:eg. eastus> --azure-resource-group <resource-group-name if created/otherwise created automatically> --azure-size <vm-name> <machine-name>

NOTE: Every Resource group has upto 10 CPU Core limit, so if you get issues creating newer instances solution is to create a new resource group.

Using Python 3 + Google Cloud Vision API's OCR to extract text from photos and scanned documents

Just a quickie test in Python 3 (using Requests) to see if Google Cloud Vision can be used to effectively OCR a scanned data table and preserve its structure, in the way that products such as ABBYY FineReader can OCR an image and provide Excel-ready output.

The short answer: No. While Cloud Vision provides bounding polygon coordinates in its output, it doesn't provide it at the word or region level, which would be needed to then calculate the data delimiters.

On the other hand, the OCR quality is pretty good, if you just need to identify text anywhere in an image, without regards to its physical coordinates. I've included two examples:
