A Keras/TensorFlow implementation of the RetinaNet object detection model with focal loss, supporting training and inference on custom datasets. The repository is deprecated in favor of torchvision's object detection module.
Use cases
- train a custom object detection model in Keras
- detect objects in images with RetinaNet
- implement focal loss for dense object detection
- fine-tune RetinaNet on MS COCO
- convert a trained detection model for inference
When to choose
- you are locked into Keras 2.4 / TensorFlow 2.3 and need RetinaNet
- you need a reference implementation of focal loss-based detection
- you want to train object detection on custom annotated datasets
When to avoid
- starting a new project - use torchvision's detection module instead
- you need support for recent TensorFlow or Keras versions
- you need actively maintained code or bug fixes
