Overview of this book

Computer vision is a crucial component of many modern businesses, including automobiles, robotics, and manufacturing, and its market is growing rapidly. This book helps you explore Detectron2, Facebook's next-gen library providing cutting-edge detection and segmentation algorithms. It’s used in research and practical projects at Facebook to support computer vision tasks, and its models can be exported to TorchScript or ONNX for deployment. The book provides you with step-by-step guidance on using existing models in Detectron2 for computer vision tasks (object detection, instance segmentation, key-point detection, semantic detection, and panoptic segmentation). You’ll get to grips with the theories and visualizations of Detectron2’s architecture and learn how each module in Detectron2 works. As you advance, you’ll build your practical skills by working on two real-life projects (preparing data, training models, fine-tuning models, and deployments) for object detection and instance segmentation tasks using Detectron2. Finally, you’ll deploy Detectron2 models into production and develop Detectron2 applications for mobile devices. By the end of this deep learning book, you’ll have gained sound theoretical knowledge and useful hands-on skills to help you solve advanced computer vision tasks using Detectron2.

Summary

This chapter introduced the techniques to fine-tune object instance segmentation applications trained using Detection2. In general, object instance segmentation applications also use object detection parts. Therefore, all the methods that are utilized to fine-tune object detection models can be used for object instance segmentation models. Additionally, this chapter discussed the PointRend project, which helps improve the object instance segmentation boundaries for the detected objects. Specifically, it described how PointRend works and the steps for developing object instance segmentation applications using the existing models available in the PointRend Model Zoo. Finally, this chapter also provided code snippets to train custom PointRend models on custom datasets.

Congratulations again! By now, you should have profound knowledge regarding Detectron2 and be able to develop computer vision applications by using existing models or training custom models on custom datasets...
