Install ImageMagick for image conversion:

brew install imagemagick

Install tesseract for OCR:

brew install tesseract --all-languages

Or install without --all-languages and install them manually as needed.

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Getting Started with a library project in Android Studio

So we're working on creating Android Material Awesome, a library which will hopefully incorperate the benefits of Material Design, Twitter's Bootstrap, and FontAwesome. What we really wanted is a project other people can easily include into their projects using gradle dependencies. To do this we needed to create a standalone library project so we could make it as lightweight as possible for including as a dependency, and a sample app that would use it for testing. These are the steps we took to get started in Android Studio (version 1.1).

Create Projects

The first thing we needed to do was to create two new projects, with all the default settings (Blank Activity etc). One for our sample app, and one for our library. We added both of ours into the same GitHub repo, however you can save them wherever you like.
