## What it is
A Keras/TensorFlow implementation of the EfficientDet object detection model with pretrained COCO and ImageNet weights. It supports training and evaluation on Pascal VOC and MSCOCO datasets, including quadrangle (oriented) object detection.

## Use cases
- train an object detection model in Keras
- run EfficientDet inference with pretrained COCO weights
- detect oriented or rotated bounding boxes (quadrangles)
- fine-tune EfficientDet on Pascal VOC or custom datasets
- evaluate object detection mAP on VOC2007 or MSCOCO

## When to choose
- you want EfficientDet specifically in the Keras/TensorFlow ecosystem
- you need oriented/quadrangle object detection support
- you want ready-to-use pretrained weights converted from the official implementation

## When to avoid
- you work in PyTorch or need the latest model features
- you need actively maintained code with recent dependency support
- you need state-of-the-art detectors beyond EfficientDet

## Facets
- artifact type: library
- maturity: maintenance
- function: machine-learning, computer-vision, image-processing
- domain: computer-vision, deep-learning, machine-learning, image-processing
- platform: python
- tags: object-detection, efficientdet, keras, tensorflow, oriented-object-detection, quadrangle-detection, pretrained-weights, coco, pascal-voc, linux, gpu
