34 Amazing Image Datasets for Your Next Computer Vision Project

What Are Image Datasets?

A dataset is a collection of data curated for a machine learning project. An image dataset includes digital images curated for testing, training, and evaluating the performance of machine learning and artificial intelligence (AI) algorithms, commonly computer vision algorithms. 

Image datasets help algorithms learn to identify and recognize information in images and perform related cognitive activities. For example, AI algorithms can be trained to tag photographs, read car plates, and identify tumors in medical images. Computer vision algorithms can also transform images or generate completely new images, with a variety of practical applications.

Below we provide a concise listing of important image datasets, categorized by their usefulness for computer vision tasks such as face detection, image segmentation, and image classification.

Face Datasets

Face datasets provide a diverse set of images containing human faces. A face dataset may include various lighting conditions, poses, emotions, and other factors like the ethnicity, age, and gender of the people in the image. 

These datasets are commonly used for facial recognition, a branch of computer vision applicable to many areas, including augmented reality, criminal justice, and personal device security.

Image Segmentation and Object Detection Datasets

Image segmentation involves breaking down an image into several segments and associating each pixel with an object type. There are two main types of segmentation—semantic segmentation, which marks all objects of the same type with one class label, and instance segmentation, which marks similar objects (for example, individual people or cars in an image) with separate labels.

Object detection involves locating instances of objects in videos or images. This technique helps machines learn how humans recognize and locate objects in images. Object detection is often performed on top of image segmentation; after an image is segmented into meaningful objects, object detection algorithms attempt to identify the class of each object.

Image datasets suitable for image segmentation and object detection projects provide images of scenes, broken down into individual objects, with ground truth annotations performed or verified by humans.
