Two-Stage Object Detection with Faster R-CNN and PyTorch

Object detection is a cornerstone of computer vision, powering everything from autonomous vehicles to retail analytics. Understanding how models locate and classify multiple objects within a single image is an essential skill for any aspiring AI practitioner. This text-based course guides you through the inner workings of two-stage object detection, focusing on the Faster R-CNN architecture. You will move from foundational computer vision concepts to configuring and fine-tuning detection models using PyTorch, gaining the skills to build and evaluate your own systems. What you'll learn: - Understand the evolution of object detection from basic R-CNN to Faster R-CNN. - Master the mechanics of Region Proposal Networks and anchor boxes for generating region candidates. - Implement Faster R-CNN models using modern PyTorch and torchvision APIs. - Apply transfer learning techniques with pre-trained backbones for custom datasets. - Evaluate model performance using standard metrics like Mean Average Precision. - Write clean, structured PyTorch code utilizing modern type hints and best practices. The course starts with essential terminology and the core concepts of bounding box regression before diving deep into the RPN architecture. You will then progress through clear, written explanations and step-by-step code walkthroughs to configure, train, and evaluate your detection models. This course is designed for beginners in computer vision who want to understand the mechanics behind modern detection systems. No prior experience with object detection is required, as we start with foundational definitions and build up your skills step-by-step.
