FiftyOne Use Cases

Dataset curation

Import, filter, query, visualize, and organize image, video, 3D, and multimodal datasets.

Outcome: More focused and usable training datasets.

Model evaluation

Compare predictions against ground truth and inspect model strengths, weaknesses, and failure cases.

Outcome: Better understanding of model performance.

Image annotation

Create or edit classifications, detections, segmentations, polygons, polylines, and keypoints in the App.

Outcome: Structured labeled datasets for machine-learning workflows.

Similarity search

Search datasets using image similarity, text similarity, or an uploaded image.

Outcome: Faster discovery of visually or semantically related samples.

Multimodal sensor analysis

Visualize, play back, tag, and query synchronized camera, LiDAR, IMU, GPS, and other sensor streams.

Outcome: Unified analysis of robotics and autonomous-vehicle recordings.

Workflow Ideas with FiftyOne

Curate and evaluate a vision dataset

  1. 1Install FiftyOne and import the dataset
  2. 2Launch the App to filter, sort, and inspect samples
  3. 3Run model predictions and evaluate them against ground truth

Create an annotated training set

  1. 1Load image or multimodal data into a FiftyOne dataset
  2. 2Annotate samples in the App or send jobs to an annotation backend
  3. 3Export the labeled dataset in the format required by the training framework

Automate model-analysis jobs

  1. 1Define a delegated operation or plugin
  2. 2Schedule it through the FiftyOne orchestrator
  3. 3Monitor background execution and review the resulting dataset fields

How FiftyOne fits into your stack

Browser

The FiftyOne App runs in a web browser for exploring images, videos, 3D data, labels, metadata, and model predictions.

Automation and APIs

Python SDK access, API keys, plugins, delegated operations, and webhooks connect FiftyOne to data and model workflows.

Knowledge and files

Teams import and manage image, video, 3D, audio, DICOM, and other multimodal datasets while preserving links to source media.

Team collaboration

FiftyOne Enterprise provides shared datasets and models, user roles, permissions, SSO, versioning, and collaborative annotation workflows.

Pros

  • +Time Efficiency: Significant reduction in development time with streamlined data workflows.
  • +Cost-Effective: Drastically lowers annotation and operational costs with advanced auto-labeling technology.
  • +Enhanced Accuracy: Improves model accuracy by providing better-curated data and evaluation tools.
  • +Comprehensive Integration: Easily integrates with existing ML stacks, supporting billions of samples.

Cons

  • −Initial Learning Curve: Users may require time to familiarize themselves with the platform's extensive features.
  • −Complexity for Small-Scale Projects: The tool's broad capabilities might be overwhelming for smaller projects or less experienced users.

Limitations & when to consider alternatives

Known limitations

  • Uploaded image queries are limited to 10 MB. The App's image-upload similarity query accepts local images under 10 MB.
  • Video workflows require FFmpeg. FFmpeg must be installed to work with video datasets and codecs.
  • Label Studio video annotation is unsupported. The documented Label Studio integration does not currently support annotating videos.
  • Datasets are non-persistent by default. Datasets created during sessions may be deleted when all Python sessions using them exit unless persistence is enabled.
  • Enterprise features require the commercial edition. Multi-user collaboration, SSO, cloud-backed media, centralized orchestration, and governance features are provided by FiftyOne Enterprise.

Look elsewhere when

  • You need a native mobile application.
  • You need a standalone desktop installer.
