Bioimage Analysis with Napari

Description: In this course, we will learn how to use the free open-source software (FOSS) Napari for bioimage analysis. Napari is a fast, interactive, multi-dimensional image viewer for Python. It's designed for browsing, annotating, and analyzing large multi-dimensional images. Being highly extensible, Napari can be used to perform state-of-the-art image analysis in a user-friendly environment. The course focuses on the practical application of Napari and requires no preliminary knowledge of Python.
