Like other image processing problems, deep learning has brought many effective solutions to the task of image segmentation. This workshop will introduce you to the methods used in image segmentation, demonstrate how to prepare your own segmentation masks using Matlab, and guide you through performing image segmentation using the FastAI [fast.ai] Python library, which is built on the deep learning library PyTorch. Some familiarity with Python is expected, but no previous experience with FastAI or PyTorch is needed. The workshop will be done online via Zoom. We will run the code using Google Colab (with free-to-use GPUs), which requires a Google account.
