Semantic Segmentation

Human-powered pixel-level image segmentation and annotation by API.

Semantic Segmentation by a human with few lines of code.
Scalable, high quality data by API.

Use Cases

Scale turns your unannotated images into annotated images with bounding boxes around objects of interest.

Self Driving Cars

Our tools and workforce are trained to assign semantic labels such as “road”, “car”, “sky”, or “person” to power the future of autonomous vehicles.


Careful semantic segmentation teaches drones to navigate around rooftops, trees and birds.


Computer vision enables robotics to tackle new horizons in manufacturing, energy and health-care.

How It Works

Send image or sensor data through our simple API and receive segmented and labeled ground truth data.

"Please segment the image using the given labels."

  instruction: 'Please segment by vehicles, pedestrians,
bikes, roads, road markings, background and obstacles
in each image.',
  attachment: '',
  labels: ['vehicle', 'background', 'road', 'vegetation',
  'lane marking']
}, (err, task) => {
    // do something with task

Scale Helps You Move Faster

We combine humans with machine learning to provide a flexible and scalable solution for impeccable ground truth training data at low cost and lightning quick turn-around.

  • Integrated with Machine Learning

    We apply machine learning in a multitude of ways to make our workforce more efficient and ensure impeccable quality and accuracy.

  • Impeccable Quality

    We have built out sophisticated quality assurance processes with in-house specialists to ensure we only produce quality results even at large scales.

  • Powerful, Beautiful Interfaces

    Our optimized interfaces allow our Scalers to be accurate, productive, and successful while working with complex and unintuitive 3D data.

  • Customer QA

    Our customers get access to the same interfaces we use internally to be able to inspect and assure quality on our results. We make it easy to check our work.

  • Customer Success Engineering

    We pair our customers with a dedicated customer success engineer who ensures smooth integration and service for our customers.

  • Built for Scale

    We process millions of tasks each month and are built to rapidly scale up and down to meet your requirements.

Scale is Trusted by World Class Companies

We already support machine learning for some of the biggest autonomous vehicle and computer vision companies in the world.
