On November 18, 2024, we have replaced the auto-labeler with a new AI-enabled labeling flow, which allows prompt-based labeling (and much more).

See the .

Our auto-labeling feature relies on the foundation model, creates embeddings or segmentation maps for your image datasets and then clusters (or groups) these embeddings based on your settings. In the Studio, you can then associate a label with a cluster and it will automatically create the labeled bounding boxes around each of the objects present in that cluster.

We developed this feature to ease your labeling tasks in your object detection projects.

Also, see our tutorial to see how to leverage the power of LLMs to automatically label your data samples based on simple prompts.

Prerequisites

  1. Make sure your project belongs to an organization. See for more info.

  2. Make sure your project is configured as an object detection project. You can change the labeling method in your project's dashboard. See for more info.

  3. Add some images to your project, either by collecting data or by uploading existing datasets. See for more info.

  4. You now should be able to see the Auto-labeler tab in your Data acquisition view:

Object detection auto-labeler settings

Which items to include:

  • All data items present in your dataset

  • Data items in the labeling queue

  • Data items without a given class

Minimum object size (pixels):

Objects smaller than this value are thrown out, an object of 20x10 pixels is 200 pixels.

Maximum object size (pixels):

Objects bigger than this value are thrown out, an object of 150x100 pixels is 15,000 pixels.

Sim threshold:

The Sim threshold corresponds to the "similarity" where 1.0 implies items are exactly the same and 0.0 are totally different. Ideal values are usually between 0.9 and 0.999, lower this value if you have too many clusters, or increase it if you notice that different objects are in the same cluster.

Click on Run the auto-labeler to generate the segmentation maps and the clusters.

Note that this process is slow (a few seconds per image, even on GPUs). However, we apply a strong cache on the results, so once you have ran the auto-labeler once, your iterations will be must faster. This will allow you to change the settings with less friction.

Label clusters

Once the process is finished, you will be redirected to a new page to associate a label with a cluster:

Select your class or create a new one for each of the clusters you want to label and click on Save the labels once you are happy with it.

Do not hesitate to go back and adjust the parameters if the clusters you don't see a clear separation, if too different objects are in the same cluster or if you have too many clusters.

Example

Each project is different, to write this documentation page, we have collected images containing several dice. This dataset can be used in several ways - you can either label the dice only, the dice color or the dice figures.

To adjust the granularity, you can use the Sim threshold parameter.

1. Group all the dice together:

Here we have been setting the Sim threshold to 0.915

2. Group the dice by color:

Here we have been setting the Sim threshold to 0.945

3. Group the dice by color and by figure:

Here we have been setting the Sim threshold to 0.98

In the public project shared above, here are the results of the trained model using the mobile phone deployment option:

You can find the dataset, with the dice labeled per color in .

Voilà! Now that you have labeled your dataset, you can and train your project.
