  • Functional Programming is a model of programming that transform and compose stream of immutable sequences by applying map, filter and reduce. Events are immutable because you can't change history.
  • Reactive Programming is a model of programming focuses on data flow and change propagation.
  • ReactiveX is an API that focuses on asynchronous composition and manipulation of observable streams of data or events by using a combination of the Observer pattern, Iterator pattern, and features of Functional Programming.
  • RxJava is the open-source implementation of ReactiveX in Java.
  • RxJava is a Java VM implementation of ReactiveX (Reactive Extensions): a library for composing asynchronous and event-based programs by using observable sequences.
  • RxAndroid is a lightweight extension to RxJava that providers a Scheduler for Android’s Main Thread, as well as the ability to create a Scheduler that runs on any given Android Handler class.
  • The two main classes are Observable and Subscriber.

Using Python 3.x and Google Cloud Vision API to OCR scanned documents to extract structured data

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:
