Dataset Card for Dataset Name

This dataset includes COCO 2017 only.

COCO 2014 and 2015 will be included soon.

Dataset Description

Homepage: https://cocodataset.org/
Repository: https://github.com/cocodataset/cocoapi
Paper: Microsoft COCO: Common Objects in Context

Dataset Summary

COCO (Common Objects in Context) is a large-scale object detection, segmentation, and captioning dataset. It contains over 200,000 labeled images with over 80 category labels. It includes complex, everyday scenes with common objects in their natural context.

This dataset covers only the "object detection" part of the COCO dataset. But some features and specifications for the full COCO dataset:

Object segmentation
Recognition in context
Superpixel stuff segmentation
330K images (>200K labeled)
1.5 million object instances
80 object categories
91 stuff categories
5 captions per image
250,000 people with keypoints

Data Splits

Training set ("train"): 118287 images annotated with 860001 bounding boxes in total.
Validation set ("val"): 5000 images annotated with 36781 bounding boxes in total.
92 classes: "None", "person", "bicycle", "car", "motorcycle", "airplane", "bus", "train", "truck", "boat", "traffic light", "fire hydrant", "street sign", "stop sign", "parking meter", "bench", "bird", "cat", "dog", "horse", "sheep", "cow", "elephant", "bear", "zebra", "giraffe", "hat", "backpack", "umbrella", "shoe", "eye glasses", "handbag", "tie", "suitcase", "frisbee", "skis", "snowboard", "sports ball", "kite", "baseball bat", "baseball glove", "skateboard", "surfboard", "tennis racket", "bottle", "plate", "wine glass", "cup", "fork", "knife", "spoon", "bowl", "banana", "apple", "sandwich", "orange", "broccoli", "carrot", "hot dog", "pizza", "donut", "cake", "chair", "couch", "potted plant", "bed", "mirror", "dining table", "window", "desk", "toilet", "door", "tv", "laptop", "mouse", "remote", "keyboard", "cell phone", "microwave", "oven", "toaster", "sink", "refrigerator", "blender", "book", "clock", "vase", "scissors", "teddy bear", "hair drier", "toothbrush", "hair brush"
But only 80 classes have with annotations: "person", "bicycle", "car", "motorcycle", "airplane", "bus", "train", "truck", "boat", "traffic light", "fire hydrant", "stop sign", "parking meter", "bench", "bird", "cat", "dog", "horse", "sheep", "cow", "elephant", "bear", "zebra", "giraffe", "backpack", "umbrella", "handbag", "tie", "suitcase", "frisbee", "skis", "snowboard", "sports ball", "kite", "baseball bat", "baseball glove", "skateboard", "surfboard", "tennis racket", "bottle", "wine glass", "cup", "fork", "knife", "spoon", "bowl", "banana", "apple", "sandwich", "orange", "broccoli", "carrot", "hot dog", "pizza", "donut", "cake", "chair", "couch", "potted plant", "bed", "dining table", "toilet", "tv", "laptop", "mouse", "remote", "keyboard", "cell phone", "microwave", "oven", "toaster", "sink", "refrigerator", "book", "clock", "vase", "scissors", "teddy bear", "hair drier", "toothbrush"

Boxes format:

For the object detection set of COCO dataset, the ground-truth bounding boxes are provided in the following format: x, y, width, height in absolute coordinates.

Curation Rationale

COCO dataset was curated with the goal of advancing the state of the art in many tasks, such as object detection, dense pose, keypoints, segmentation and image classification.

Loading dataset

You can load COCO 2017 dataset by calling:

from datasets import load_dataset
# Full dataset
dataset = load_dataset("rafaelpadilla/coco2017")
print(dataset)
>> DatasetDict({
>>     train: Dataset({
>>         features: ['image', 'image_id', 'objects'],
>>         num_rows: 118287
>>     })
>>     val: Dataset({
>>         features: ['image', 'image_id', 'objects'],
>>         num_rows: 5000
>>     })
>> })

# Training set only
dataset = load_dataset("rafaelpadilla/coco2017", split="train")

# Validation set only
dataset = load_dataset("rafaelpadilla/coco2017", split="val")

COCODataset Class

We offer the dataset class COCODataset that extends VisionDataset to represents images and annotations of COCO. To use it, you need to install coco2017 package. For that, follow the steps below:

Create and activate an environment:

conda create -n coco2017 python=3.11 
conda activate coco2017

Install cocodataset package:

pip install git+https://huggingface.co/datasets/rafaelpadilla/coco2017@main

or alternatively:

git clone https://huggingface.co/datasets/rafaelpadilla/coco2017
cd coco2017
pip install .

Now you can import COCODataset class into your Python code by:

from cocodataset import COCODataset
