# EfficientDet: Scalable and Efficient Object Detection
## Introduction
Here is our pytorch implementation of the model described in the paper **EfficientDet: Scalable and Efficient Object Detection** [paper](https://arxiv.org/abs/1911.09070) (*Note*: We also provide pre-trained weights, which you could see at ./trained_models)

## Datasets
| Dataset | Classes | #Train images | #Validation images |
|------------------------|:---------:|:-----------------------:|:----------------------------:|
| COCO2017 | 80 | 118k | 5k |
Create a data folder under the repository,
```
cd {repo_root}
mkdir data
```
- **COCO**:
Download the coco images and annotations from [coco website](http://cocodataset.org/#download). Make sure to put the files as the following structure:
```
COCO
├── annotations
│ ├── instances_train2017.json
│ └── instances_val2017.json
│── images
├── train2017
└── val2017
```
## How to use our code
With our code, you can:
* **Train your model** by running **python train.py**
* **Evaluate mAP for COCO dataset** by running **python mAP_evaluation.py**
* **Test your model for COCO dataset** by running **python test_dataset.py --pretrained_model path/to/trained_model**
* **Test your model for video** by running **python test_video.py --pretrained_model path/to/trained_model --input path/to/input/file --output path/to/output/file**
## Experiments
We trained our model by using 3 NVIDIA GTX 1080Ti. Below is mAP (mean average precision) for COCO val2017 dataset
| Average Precision | IoU=0.50:0.95 | area= all | maxDets=100 | 0.314 |
|-----------------------|:-------------------:|:-----------------:|:-----------------:|:-------------:|
| Average Precision | IoU=0.50 | area= all | maxDets=100 | 0.461 |
| Average Precision | IoU=0.75 | area= all | maxDets=100 | 0.343 |
| Average Precision | IoU=0.50:0.95 | area= small | maxDets=100 | 0.093 |
| Average Precision | IoU=0.50:0.95 | area= medium | maxDets=100 | 0.358 |
| Average Precision | IoU=0.50:0.95 | area= large | maxDets=100 | 0.517 |
| Average Recall | IoU=0.50:0.95 | area= all | maxDets=1 | 0.268 |
| Average Recall | IoU=0.50:0.95 | area= all | maxDets=10 | 0.382 |
| Average Recall | IoU=0.50:0.95 | area= all | maxDets=100 | 0.403 |
| Average Recall | IoU=0.50:0.95 | area= small | maxDets=100 | 0.117 |
| Average Recall | IoU=0.50:0.95 | area= medium | maxDets=100 | 0.486 |
| Average Recall | IoU=0.50:0.95 | area= large | maxDets=100 | 0.625 |
