# 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!
