FDDB-Create-Format-Annotations

Most face detection repositories only support COCO format and Widerface format annotations. However. original FDDB dataset does not provide such annotations. This project helps create COCO format and Widerface format annotation files for FDDB.

Use Annotations

We provide annotation files in COCO and Widerface format for 10-fold cross validation. You can find them in annotations/COCO/ and annotations/Widerface/ . Since there is no key point ground truth in FDDB dataset, we simply fake key points.

COCO format example:

{"info": 
 	{"description": "FDDB in COCO format.", 
     "url": "", 
     "version": "1.1", 
     "contributor": "SSRSGJYD", 
     "date_created": "2020-11-15"}, 
 "images": [
     {"file_name": "2002/08/11/big/img_591.jpg", 
      "coco_url": "local", 
      "height": 431, 
      "width": 450, 
      "flickr_url": "local", 
      "id": 1}, 
     ...], 
 "annotations": [
     {"segmentation": [], 
 	  "num_keypoints": 5, 
 	  "keypoints": [0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1], 
 	  "iscrowd": 0, 
 	  "area": 43139, 
 	  "image_id": 1, 
 	  "bbox": [180, 41, 179, 241],
      "category_id": 1, 
      "id": 1}, 
	...]
}

Widerface format example:

# 2002/08/11/big/img_591.jpg
180 41 179 241 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Create Annotations By Yourself

Our code works in Python 3.x environments. Install requirements by:

pip3 install -r requirements.txt

Download FDDB dataset from here and decompress the two folders into /fddb/images/ .

To create COCO format annotations:

python fddb2coco.py

To create Widerface format annotations:

python fddb2txt.py
