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:

Introduction

I recently needed to apply CORS (Cross Origin Request Scripting) to a project that I'm working on. If found 2 posts that helped to achieve it:

I combined both to solve my problem: I have a User CRUD (Play!) webservice and a (Play!) web app that services a SPA (Single Page Application). The SPA needs to access the CRUD webservice, but to acheive this, I would need to apply some CORS rules on both applications.

Configure Synology NAS as Git Server

Instructions for setting up a git server on a Synology NAS with Diskstation. Specifically, I am using a DS414 with DSM 5.0.

Set Up User and Folder

Create user gituser via Diskstation interface (with File Station and WebDAV privilages)
Add new shared folder called git (located at /volume1/git) with read/write access for gituser and admin. This folder will hold all the repos.
Install Git Server package via Diskstation

	* Unfortunately it by default requires a Play application context.
	* But you do not necessarily always want that.
