scikit-image was founded in 2009 by Stéfan van der Walt.  It is a community-driven Python project, consisting of a vast collection of high-quality, peer-reviewed image processing algorithms that are made available to a global community of researchers free of charge and free of restriction.  The library is widely used in many different fields, including astronomy, biomedical imaging, and environmental resource management. The library builds on NumPy and SciPy, two other projects in the scientific Python ecosystem supported by BIDS.
