What is Data Curation in Computer Vision?

Data curation is a relatively new focus area for Machine Learning teams. Essentially it covers the management and handling of data across your MLOps pipeline. More specifically It refers to the process of 1) collecting, 2) cleaning, 3) organizing, 4) evaluating, and 5) maintaining data to ensure its quality, relevance, and suitability for your specific computer vision task. 

In recent times it has also come to refer to finding model edge cases and surfacing relevant data to improve your model performance for these cases.

Before the entry of the data curation paradigm, Data Scientists and Data Operation teams were simply feeding their labeling team raw visual data which was labeled and sent for model training. As training data pipelines have matured this strategy is not practical and cost-effective anymore.

This is where good data curation enters the picture.

Without good data curation practices, your computer vision models may suffer from poor performance, accuracy, and bias, leading to suboptimal results and even failure in some cases. 

Furthermore, once you’re ready to scale your computer vision efforts and bring multiple models into production, the task of funneling important production data into your training data pipeline and prioritizing what to annotate next becomes increasingly challenging. In the base case, you’d want a structured approach, and in the best case a highly automated data-centric approach.

Lastly, as you discover edge cases for your computer vision models in a production environment, you would need to have a clear and structured process for identifying what data to send for labeling to improve your training data and cover the edge case. 

Therefore, having the right data curation tools is crucial for any computer vision project.

What to Consider in a Data Curation Tool in Computer Vision?

Having worked with hundreds of ML and Data Scientist teams deploying thousands of models into production every year, we have gathered a comprehensive list of best practices when selecting a tool. The list is not 100% exhaustive, so if you have anything you would like to add we would love to hear from you here.

Data Prioritization

Selecting the right data is crucial for training and evaluating computer vision models. A good data curation tool should have the ability to filter, sort, and select the appropriate data for a given task. This includes being able to handle large datasets, as well as the ability to select data based on certain attributes or labels. If the tool supports reliable automation features for data prioritization that is a big plus. 

Visualizations

Customizable visualization of data is important for understanding and analyzing large datasets. A good tool should be able to display data in various forms such as tables, plots, and images, and allow for customization of these visualizations to meet the specific needs of the user.

Model-Assisted Insights

Model-assisted debugging is another important feature of a data curation tool. This allows for the visualization and analysis of model performance and helps to identify issues that may be present in the data or the model itself. This can be achieved through features such as confusion matrices, class activation maps, or saliency maps.

Modality Support

Support for different modalities is also important for computer vision. A good data curation tool should be able to handle multiple different types of data such as images, videos, DICOM, and geo. tiff, while extending support to all annotation formats such as bounding boxes, segmentation, polyline, keypoint, etc.

Data Management

The data curation tool should efficiently handle large image datasets, offer seamless import/export functionalities, and provide effective organization features like hierarchical folders, tagging, and metadata management. It should support annotation versioning and quality control to ensure data integrity and consistency.

Simple & Configurable User Interface (UI)

A data curation tool is often used by multiple technical and non-technical stakeholders. Thus a good tool should be easy to navigate and understand, even for those with little experience in computer vision. Setting up recurring automated workflows should be supported while programmatic support for webhooks, API calls, and SDK should also be available.

Annotation Integration

Recurring annotation and labeling a crucial part of data curation for computer vision. A good tool should have the ability to easily support annotation workflows and allow for the creation, editing, and management of labels and annotations. 

Collaboration

Collaboration is also important for data curation. A good tool should have the ability to support multiple users and allow for easy sharing and collaboration on datasets and annotations. This can be achieved through features such as shared annotation projects and real-time collaboration.

Why Is Data Curation Important in Computer Vision?

Data curation is critical in computer vision because it directly affects the performance and accuracy of models. Computer vision models rely on large amounts of data to learn and make predictions, and the quality and relevance of that data determine the model's ability to generalize and adapt to new situations.

Conclusion

Data curation is a crucial aspect of any computer vision project. Without good data curation practices, your models may suffer from poor performance, accuracy, and bias. To ensure the best results, it is essential to have the right data curation tools. 

In this article, we have covered the top 7 data curation tools for computer vision of 2023, comparing them based on criteria such as annotation support, features, customization, data privacy, data management, data visualization, integration with the machine learning pipeline, and customer support.

 We hope that this article has provided valuable information and insights to help you make an informed decision on which data curation tool is best for your specific use case and budget.
