This repository contains training resources for Python beginners who want to dive into image processing with Python. It specifically aims for students and scientists working with microscopy images in the life sciences. We start with Python basics, image processing, dive into descriptive statistics for working with measurements and matplotlib and seaborn for plotting results. Furthermore, we will process data and images with numpy, scipy, scikit-image and clEsperanto. We will explore napari for interactive image data analysis and scikit-learn and apoc for processing image using machine learning.
The material will develop between April and July 2023. The materials from former years are linked below.
You can browse the material online for taking a quick look.
If you want to do the exercises, it is recommended to download the whole repository, e.g. by hitting the code button in the top right corner and clicking on download.
Unzip the downloaded zip-file and navigate inside the sub folders, e.g. using the command prompt.
In order to execute code and do the exercises, you need to install conda, which will be explained in the first lesson.
This course explains everything in very detail. Every lesson ends with an exercise and it is recommended to do it before moving on to the next lesson. If you have Python basics knowledge already, test yourself by doing these exercises before starting with an advanced lesson.
