|
|
|
|
OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library. OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products. Being a BSD-licensed product, OpenCV makes it easy for businesses to utilize and modify the code.

|
To install OpenCV on OSX using Homebrew:
|
|
|
|
```
|
|
$ brew tap homebrew/science && brew install opencv
|
|
```
|
|
|
|
### Ubuntu
|
|
|
|
To install OpenCV on Ubuntu 14.04:
|
|
|
|
```
|
|
$ sudo apt-get install libopencv-dev
|
|
```
|
|
|
|
Or, follow the official [OpenCV installation guide](http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html)

|
|
Follow the official [OpenCV installation guide](http://docs.opencv.org/doc/tutorials/introduction/windows_install/windows_install.html#windows-installation)
|
|
|
|
|
|
Now you can install the package with
|
|
```
|
|
go get -d -u gobot.io/x/gobot/...
