In the realm of computer vision, where machines are becoming increasingly adept at understanding and interpreting visual information, the importance of high-quality datasets cannot be overstated. These collections of labeled images have become the cornerstone of training computer vision algorithms, enabling them to perceive the world with high accuracy. Whether it's object recognition, image classification, segmentation, or scene understanding, the availability of diverse datasets is crucial for driving advancements.

Recognising the significance of these datasets, we have curated a list of the 10 best datasets for computer vision.

Microsoft COCO:


Widely regarded as a benchmark in the community, COCO encompasses a massive collection of labeled images, designed to facilitate research in object recognition, segmentation, and captioning, pushing the boundaries of visual understanding and fostering innovation in computer vision algorithms. COCO is a large-scale object detection, segmentation, and captioning dataset developed by Microsoft. It’s features are the following:

  • Use cases: object segmentation, recognition in context
  • Dataset: 330K images (>200K labeled) with 5 captions per image. The dataset contains 1.5 million object instances, and 250K people with key points
  • Classes: 80 object categories, 91 “stuff” categories
  • License: Commercial as well as research purposes

CIFAR-10 & CIFAR-100:

The CIFAR-10 dataset, which stands for Canadian Institute For Advanced Research, comprises a diverse collection of images specifically curated for training machine learning and computer vision algorithms. Renowned as one of the most extensively employed datasets in the field of machine learning research, it serves as a benchmark for numerous experiments and evaluations. The dataset is organised into five training batches and one test batch, with each batch containing 10,000 images. The test batch includes 1,000 randomly selected images from each class, while the training batches have the remaining images, with a balanced distribution of 5,000 images from each class.

  • Use case: image classification
  • Dataset: 60k color images (32x32 pixels) split into 50k training and 10k testing subsets. The dataset contains 6000 images per class
  • Classes: 10
  • License: Commercial purposes must be discussed with the provider of this dataset.

CIFAR-100, similar to CIFAR-10, is a dataset that consists of 100 classes, with each class comprising 600 images. The dataset is split into 500 training images and 100 testing images per class. What sets CIFAR-100 apart is that its 100 classes are organised into 20 broader superclasses. 

Each image within the dataset is assigned both a "fine" label, representing its specific class, and a "coarse" label, representing the superclass to which it belongs. This hierarchical labeling system allows for more detailed and higher-level categorisation within the CIFAR-100 dataset.

  • Use case: image classification
  • Dataset: 60k color images (32x32 pixels) split into 50k training and 10k testing subsets. The dataset contains 600 images per class
  • Classes: 100 classes, and are organised into 20 broader superclasses
  • License: Commercial purposes must be discussed with the provider of this dataset.

Fashion MNIST

Fashion-MNIST, created by Zalando, is a dataset consisting of 70,000 grayscale images of fashion articles, with 60,000 examples for training and 10,000 for testing. Each image is a 28x28 pixel grayscale image, labeled into one of 10 classes. Fashion-MNIST is designed to be a drop-in replacement for the original MNIST dataset, allowing researchers to benchmark their machine learning algorithms using the same image size and training/testing splits. Zalando aims to replace the original MNIST dataset and provide a more diverse alternative for evaluating algorithm performance in the AI/ML/Data Science community.
