Open Datasets

One of the best places to look for quality open source datasets is our own repository. You can use advanced filtering options and the search box to look for very specific datasets.

For example, if you’re only interested in a specific licence, such as public domain datasets, make sure to select the CC-0 option in the licence filter.

You can combine various filtering options to narrow down your search.

If you haven’t found what you’re looking for among the 500+ open datasets we’ve catalogued here, don’t despair—there are other places you may want to visit.

Start with these articles:

• 20+ Best Image Datasets for Computer Vision
• 65+ Best Free Datasets for Machine Learning
• 21+ Best Healthcare Datasets for Computer Vision

Each of them comes with detailed descriptions and links to online datasets for various purposes.

Yes, all sample datasets in our repository can be imported into V7.

Open datasets offer a number of benefits for computer vision projects. Firstly, they allow for easier collaboration between researchers. When data is openly available, researchers can more easily share and build upon each other’s work. This helps to accelerate the pace of research and allows for more innovative solutions to be found.

Secondly, open datasets help to ensure that the data used is of high quality. When data is openly available, it is subject to greater scrutiny from the research community. This helps to ensure that any flaws or errors in the data are quickly identified and corrected.

Finally, open datasets allow for replicability of results. When data is openly available, researchers can more easily check and verify each other’s results. This helps to build confidence in the findings of a study and allows for more reliable conclusions to be drawn.

Yes, all the online datasets in our repository are free to use. The only limitations may involve the scope of usage or requirements to attribute the dataset to its source. You can easily see what licence a given open dataset falls under on each dataset’s dedicated page.

Our repository of open image datasets consists of free public datasets for computer vision projects. For your convenience we’ve divided them into several categories, e.g.:

Computer vision task types

• Image classification datasets
• Object detection datasets
• Segmentation datasets

Use cases

• Person detection dataset
• Face detection dataset
• Anime face dataset
• Image-text pair dataset (LAION-400M)
• COCO datasets
• Furniture image dataset
• Animal datasets
• Covid-19 xray dataset

In fact, you can use advanced filtering options to browse our open image datasets by tasks, annotation types, use cases, or licence. Additionally, you can look for interesting datasets by typing a keyword or sorting the results alphabetically, by popularity or the number of images in the dataset.

An open dataset for machine learning is a dataset that is freely available for anyone. You can use them as datasets for projects to train and test your machine learning models.
