## Requirements:

FastDRaW requires the following packages

Or run

`shell sudo apt-get install build-essential python2.7-dev sudo pip install -r requirements.txt `

## Install:

From PyPI:

`shell sudo pip install FastDRaW ` From git repository:

`shell git clone cd FastDRaW-Segmentation sudo python install `

## Usage example:

`python >>> from FastDRaW import Segmenter >>> from import coins >>> import matplotlib.pyplot as plt >>> image = coins() >>> labels = np.zeros_like(image) >>> labels[[129, 199], [155, 155]] = 1 # label some pixels as foreground >>> labels[[162, 224], [131, 184]] = 2 # label some pixels as background >>> fastdraw = Segmenter(image, beta=100, downsampled_size=[100,100]) >>> segm = fastdraw.update(labels) >>> plt.imshow(image,'gray') >>> plt.imshow(segm, alpha=0.7) `
