scikit-image (formerly scikits.image) is an open-source image processing library for the Python programming language.

[2] It includes algorithms for segmentation, geometric transformations, color space manipulation, analysis, filtering, morphology, feature detection, and more.

[3] It is designed to interoperate with the Python numerical and scientific libraries NumPy and SciPy.

The scikit-image project started as scikits.image, by Stéfan van der Walt.

Of the various scikits, scikit-image as well as scikit-learn were described as "well-maintained and popular" in November 2012[update].
