Essential Pil (Pillow) Image Tutorial (For Machine Learning People)

Derrick Mwiti's blog post on the Neptune platform provides an in-depth tutorial on using Pillow, a fork of the Python Image Library (PIL), for image processing tasks crucial in machine learning, particularly in computer vision. The article emphasizes the importance of Pillow over the outdated PIL, highlighting its ease of use and popularity among Python users. It covers essential concepts such as image bands, modes, and the Cartesian pixel coordinate system, and delves into practical applications like reading and writing images, image manipulation (including cropping, rotating, merging, and flipping), and enhancement with filters and transformations. It also explores advanced functionalities like handling image sequences (GIFs) and converting images to NumPy arrays. The tutorial concludes by suggesting Pillow’s utility in augmenting training data for deep learning, thereby boosting model performance, and encourages readers to apply these techniques in their image processing workflows.
