# Image processing examples with Numpy, Scipy, and Scikit-image

### Requirements

* **Python 3.4+**
* **NumPy (`$ pip install numpy`)**
* **SciPy (`$ pip install scipy`)**
* **MatplotLib (`$ pip install matplotlib`)**
* **Scikit-image (`$ pip install scikit-image`)**

---

### Testing after install

Open a Jupyter notebook and execute the following code,
```
import numpy as np
import matplotlib.pyplot as plt
from skimage import data, io, filters

image = data.coins() # or any NumPy array!
edges = filters.sobel(image)
io.imshow(edges)
```

You should see the following output. If you see this, you are all set to go!
