## Description

[`Rvision`](https://github.com/swarm-lab/Rvision) is a growing computer vision 

library for [`R`](https://cran.r-project.org). It is based on the powerful 

[`OpenCV`](http://opencv.org/) library for C/C++, the state-of-the-art for 

computer vision in the open source world. 

The ultimate goal of [`Rvision`](https://github.com/swarm-lab/Rvision) is to 

provide `R` users with all the necessary functions to read and manipulate images, 

videos and camera streams, with an emphasis on speed (thanks to `OpenCV`). In 

this respect, it is different from all the other image manipulations packages 

for `R` that either can not quickly and directly access frames from videos and 

camera streams or are limited in their processing speed and/or volume.

## FAQ

### Can I take selfies with my webcam using [`Rvision`](https://github.com/swarm-lab/Rvision)?

You certainly can, but ask yourself first whether you should...

```r

my_stream <- stream(0)   # 0 will start your default webcam in general. 

my_selfie <- readNext(my_stream)

plot(my_selfie)

release(my_stream)

```

Be careful, this will trigger the explosion of your camera if it detects that 

you are making a duck face ;-)
