Detectron
Detectron is a PyTorch object detection framework and computer vision research platform. It provides implementations of neural network architectures for locating and identifying objects in images, including Mask R-CNN for generating instance segmentation masks and RetinaNet for one-stage detection.
The platform supports computer vision prototyping and object detection research through the deployment of pre-trained baseline models. This allows for the rapid implementation and evaluation of visual recognition systems.
Its capabilities cover image object localization and instance segmentation workflows. These are supported by structural components such as feature pyramid networks, region-based convolutional networks, and two-stage detection pipelines.
