COCO is a large-scale object detection, segmentation, and captioning dataset.

Note: * Some images from the train and validation sets don't have annotations. * Coco 2014 and 2017 uses the same images, but different train/val/test splits * The test split don't have any annotations (only images). * Coco defines 91 classes but the data only uses 80 classes. * Panotptic annotations defines defines 200 classes but only uses 133.

To use this dataset:

import tensorflow_datasets as tfds

ds = tfds.load('coco', split='train')
for ex in ds.take(4):
 print(ex)

Microsoft Common Objects in Context (COCO) Dataset

The Common Objects in Context (COCO) dataset is a widely recognized collection designed to spur object detection, segmentation, and captioning research. Created by Microsoft, COCO provides annotations, including object categories, keypoints, and more. The model it a valuable asset for machine learning practitioners and researchers. Today, many model architectures are benchmarked against COCO, which has enabled a standard system by which architectures can be compared.

While COCO is often touted to comprise over 300k images, it's pivotal to understand that this number includes diverse formats like keypoints, among others. Specifically, the labeled dataset for object detection stands at 123,272 images.

The full object detection labeled dataset is made available here, ensuring researchers have access to the most comprehensive data for their experiments. With that said, COCO has not released their test set annotations, meaning the test data doesn't come with labels. Thus, this data is not included in the dataset.

The Roboflow team has worked extensively with COCO. Here are a few links that may be helpful as you get started working with this dataset:

A dataset for object detection with various 1L + images of subjects and objects

Context

This dataset contains pickled Python objects with data from the annotations of the Microsoft (MS) COCO dataset. COCO is a large-scale object detection, segmentation, and captioning dataset.

Content

Except for the objs file, which is a plain text file continuing a list of objects, the data in this dataset is all in the pickle format, a way of storing Python objects at binary data files.

Important: These pickles were pickled using Python 2. Since Kernels use Python 3, you will need to specify the encoding when unpickling these files. The Python utility scripts here have been updated to correctly unpickle these files.

# the correct syntax to read these pickled files into Python 3
pickle.load(open('file_path, 'rb'), encoding = "latin1")

  Dataset Summary

COCO is a large-scale object detection, segmentation, and captioning dataset. This repo contains five captions per image; useful for sentence similarity tasks. Disclaimer: The team releasing COCO did not upload the dataset to the Hub and did not write a dataset card. These steps were done by the Hugging Face team.

COCO semantic segmentation maps

This dataset contains semantic segmentation maps (monochrome images where each pixel corresponds to one of the 133 COCO categories used for panoptic segmentation). It was generated from the 2017 validation annotations using the following process:

COCO (Common Objects in COntext) is a popular dataset in Computer Vision. It contains annotations for Computer Vision tasks - object detection, segmentation, keypoint detection, stuff segmentation, panoptic segmentation, densepose, and image captioning. For more details visit COCO Dataset

The Tensor Processing Unit (TPU) hardware accelerators are very fast. The challenge is often to feed them data fast enough to keep them busy. Google Cloud Storage (GCS) is capable of sustaining very high throughput but as with all cloud storage systems, initiating a connection costs some network back and forth. Therefore, having our data stored as thousands of individual files is not ideal. This dataset contains COCO dataset with object detection annotations in a smaller number of files and you can use the power of tf.data.Dataset to read from multiple files in parallel.

TFRecord file format Tensorflow's preferred file format for storing data is the protobuf-based TFRecord format. Other serialization formats would work too but you can load a dataset from TFRecord files directly by writing:

filenames = tf.io.gfile.glob(FILENAME_PATTERN) dataset = tf.data.TFRecordDataset(filenames) dataset = dataset.map(...)

You can use the following code in your kaggle notebook to get Google Cloud Storage (GCS) path of any public Kaggle dataset .

from kaggle_datasets import KaggleDatasets
GCS_PATH = KaggleDatasets().get_gcs_path()

This repository contains a mapping between the classes of COCO, LVIS, and Open Images V4 datasets into a unique set of 1460 classes.

COCO [Lin et al 2014] contains 80 classes, LVIS [gupta2019lvis] contains 1460 classes, Open Images V4 [Kuznetsova et al. 2020] contains 601 classes.

We built a mapping of these classes using a semi-automatic procedure in order to have a unique final list of 1460 classes. We also generated a hierarchy for each class, using wordnet

This repository contains the following files:

coco_classes_map.txt, contains the mapping for the 80 coco classes

lvis_classes_map.txt, contains the mapping for the 1460 coco classes

openimages_classes_map.txt, contains the mapping for the 601 coco classes

classname_hyperset_definition.csv, contains the final set of 1460 classes, their definition and hierarchy

all-classnames.xlsx, contains a side-by-side view of all classes considered

This mapping was used in VISIONE [Amato et al. 2021, Amato et al. 2022] that is a content-based retrieval system that supports various search functionalities (text search, object/color-based search, semantic and visual similarity search, temporal search). For the object detection VISIONE uses three pre-trained models: VfNet Zhang et al. 2021, Mask R-CNN He et al. 2017, and a Faster R-CNN+Inception ResNet (trained on the Open Images V4).
