Image Segmentation with PyTorch: Practical Projects and Techniques

Computer vision is transforming industries from healthcare to autonomous driving, and image segmentation is at the heart of this revolution. Understanding how to classify every pixel in an image allows you to extract precise, actionable data from visual sources. This written course guides you from the fundamental principles of pixel-level classification to implementing robust deep learning architectures. By reading through clear explanations and studying curated code examples, you will gain the skills to prepare datasets, build segmentation networks, and evaluate their performance on real-world scenarios. What you'll learn: Understand the foundational concepts of semantic and instance segmentation; Configure data pipelines using PyTorch Dataset and DataLoader classes; Build popular segmentation architectures like U-Net from scratch; Apply transfer learning using pre-trained models from torchvision; Evaluate model performance using metrics like Intersection over Union (IoU) and Dice coefficient; Implement loss functions tailored for class imbalance, such as Dice loss and focal loss. The course begins with essential terminology and the mathematical foundations of pixel classification before moving into practical PyTorch implementations. You will walk through the entire workflow, from preprocessing raw images to optimizing and testing your trained models. This course is designed for beginners in computer vision and deep learning; familiarity with basic Python programming is helpful, but no prior experience with image segmentation is required.
