Scikit-image 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. Scikit-image was founded by BIDS Research Data Scientist Stéfan van der Walt in 2009.


Mothra analyzes images of butterflies and measures their wing lengths. Using binarization techniques and calculating the resolution of ruler ticks, we read in images of butterflies and output the millimeter lengths of their wings.

The pipeline script combines four modules to analyze an image: ruler detection, binarization, tracing, and final measurement. These modules are located in /butterfly . Python module requirements are listed in requirements.txt .
