Android is awesome, and so is OpenCV, so wouldn't it be awesomer if they could work together? Well they can, and its now officially supported in OpenCV! See the Android Release Notes.

How to start

Developers have 2 basic ways to develop applications with the OpenCV4Android:
  1. We recommend to download the prebuilt OpenCV package and follow the instructions from our tutorial: Using Android binary package with Eclipse (start from here). This package contains Eclipse library project and samples. Package also includes prebuilt apk-files, which you can run on your device immediately. They are placed at OpenCV-2.4.0/bin folder inside the binary package.
  2. You can build OpenCV from sources and have the full control over the library. See the OpenCV trunk for Android page for instructions. Please note, that this is not recommended way and think twice before you checkout the OpenCV sources.
