We’re building a data-first marketplace, one where data and assets can be shared and traded.

The marketplace will contain all that this report contains (and much more for a lot more datasets). The report was created to help readers quickly find common resources and/or assets for a given dataset and a specific task, in this case dataset=COCO, task=object detection. I’m open to suggestions, questions, and criticism. Please email me or message me to start a conversation.

I have broken up the report into the following blogs:

  1. Part 1: COCO Summary Card. Each link will take you to the longer report where you can learn more. The next 3 parts represent a specific section in the report

About COCO (Common Objects in Context)

Who: Microsoft

Year released: The first version of MS COCO dataset was released in 2014.

Description

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

  • 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

image

List of the COCO Object Classes: The COCO dataset classes include the following pre-trained 80 objects. Click here to see the representation of these objects in the dataset.

The first version of MS COCO dataset was released in 2014. It contains 164,000 images split into training (83,000), validation (41,000) and test (41,000) sets. In 2015 an additional test set of 81,000 images was released, including all the previous test images and 40,000 new images.

Based on community feedback, in 2017 the training/validation split was changed from 83K/41K to 118K/5K. The new split uses the same images and annotations. The 2017 test set is a subset of 41K images of the 2015 test set. Additionally, the 2017 release contains a new unannotated dataset of 123K images.

Structure and format

The “COCO format” is the following JSON structure, which also includes labels and metadata:

  • Info: Provides a high-level description and versioning information about your dataset.
  • Licenses: Provides a list of image licenses with unique IDs to be specified by your images. It specifies the copyright to use the image.
  • Images: Provides a list of images and relevant metadata.
  • Categories: Provides a list of classification categories and supercategories of objects that are present in an image, each with a unique ID. (Note if you want to use a model pretrained on COCO out of the box, then you’d need to follow the COCO classes/categories).
  • Annotations: Provides annotations each with a unique ID and the image ID it relates to. This contains the metadata about the categories related to an object, such as the location, size, and object category.

Tasks

This dataset is used to set benchmarks for the following tasks: object detection, panoptic semantic segmentation, keypoint detection, dense pose estimation.

Object Detection: Objects are annotated with a bounding box and class label

image
Panoptic Semantic Segmentation: The boundary of objects are labeled with a mask and object classes are labeled with a class label

image

Keypoint Detection: This task involves simultaneously detecting people and localizing their keypoints.

image

DensePose: Involves mapping all human pixels of an RGB image to the 3D surface of the human body.

In this document, we will mainly focus on object detection. Please read Object Detection in 2022: The Definitive Guide and A Beginner’s Guide to Object Detection for quick tutorials on object detection (more detailed tutorials are available throughout the document.)

Evaluation metrics

DataTorch

About

“Easily collaborate on custom computer vision datasets.”


DataTorch has an open source (https://open.datatorch.io/) collaborative data annotation tool where you can plug in any cloud storage, annotate files with your team, and export in COCO and other formats. You can also work online on the platform. DataTorch is a developer tool for building computer vision models. DataTorch revolves around the management of projects, which encapsulate of all of the data, people, and work related to a particular model.

Tutorials

  2. Quickstart | DataTorch Documentation: Get started annotating a dataset and exporting it in COCO format right away.
  3. Building Computer Vision Datasets in Coco Format — YouTube: “Analyzing visual environments is a major objective of computer vision; it includes detecting what items are there, localizing them in 2D and 3D, identifying their properties, and describing their relationships. As a result, the dataset could be used to train item recognition and classification methods. COCO is frequently used to test the efficiency of real-time object recognition techniques. Modern neural networking modules can understand the COCO dataset’s structure. Contemporary AI-driven alternatives are not quite skillful in creating complete precision in findings that lead to a fact that the COCO dataset is a substantial reference point for CV to train, test, polish, and refine models for faster scaling of the annotation pipeline. The COCO standard specifies how your annotations and picture metadata are saved on disc at a substantial stage. Furthermore, the COCO dataset is an addition to transfer learning, in which the material utilized for one model is utilized to start another.”

  2. Explore the Coco Captions dataset: KYD allows you to explore fairness and bias issues by comparing features. You can see how labels correlate with protected entities.
  3. A Dataset Exploration Case Study with Know Your Data: “We demonstrate some of the functionality of a dataset exploration tool, Know Your Data (KYD), recently introduced at Google I/O, using the COCO Captions dataset as a case study. Using this tool, we find a range of gender and age biases in COCO Captions — biases that can be traced to both dataset collection and annotation practices. KYD is a dataset analysis tool that complements the growing suite of responsible AI tools being developed across Google and the broader research community. Currently, KYD only supports analysis of a small set of image datasets, but we’re working hard to make the tool accessible beyond this set.”

OpenCV

About

OpenCV (Open Source Computer Vision Library) is a library of programming functions mainly aimed at real-time computer vision. It is a software toolkit for processing real-time image and video, as well as providing analytics, and machine learning capabilities. It was originally created in 2000 by Intel. Github: https://github.com/opencv/opencv. According to Intel, “using OpenCV developers can access many advanced computer vision algorithms used for image and video processing in 2D and 3D as part of their programs. The algorithms are otherwise only found in high-end image and video processing software.”


OpenCV provides several modules for working on computer vision problems that are supported on the current popular deep learning frameworks: Tensorflow, Keras, and PyTorch.

OpenCV’s trained models can be executed on CPUs or NVIDIA or Intel GPUs. OpenVINO (see below) optimizes running OpenCV capabilities on Intel hardware.


OpenCV also has launched both a) hardware devices called the OpenCV AI Kit (OAK) (OAK-1 or OAK-D) and b) OpenCV AI Marketplace. “

OAK is a modular, open-source ecosystem composed of MIT-licensed hardware, software, and AI training — that allows you to embed the super-power of spatial AI plus accelerated computer vision functions into your product. OAK provides in a single, cohesive solution what would otherwise require cobbling together disparate hardware and software components.


The marketplace is called modeplace.ai and was built with OAK in mind.
