scikit-image and the Scientific Python ecosystem. Images are opened from files as NumPy arrays. Functions of scikit-image transform image arrays into other arrays with the same dimensions, or into arrays of numbers corresponding to features of the image. The output of scikit-image functions can be passed to other Python modules relying on NumPy arrays, such as SciPy or scikit-learn. Image-shaped arrays are transformed into visualizations with matplotlib (2D) or Mayavi (3D). A variety of environments is available for code development and execution, from classical IDEs to Jupyter notebooks
