Convert annotation formats

How To Convert Marmot XML to Sagemaker GroundTruth Manifest

In this guide, we show you how to convert data between the Marmot and GroundTruth formats for free. You can use your converted data to train models and other models that support the GroundTruth format.

Marmot XML

Marmot is an obscure Chinese annotation format created by researchers at Peking University.

Below, learn the structure of Marmot XML.

Step 1: Create a free Roboflow account

Roboflow is a universal conversion tool for computer vision annotation formats. To convert your dataset, start by creating a free Roboflow account.

Create free Roboflow account

Step 2: Upload your data into Roboflow

Once your account has been created, click Create New Project. (opens in a new tab)

Roboflow's create project form, with Object Detection selected as the project type

Upload your data to Roboflow by dragging and dropping your Marmot XML images and annotations into the upload space.

Roboflow's upload page, with a drag-and-drop area for images, annotations, videos and PDFs

Step 3: Generate Dataset Version

Next, click "Generate New Version" to generate a new version of your dataset:

Roboflow's Generate a Dataset Version page, showing the source images and train/test split for a new version

You can then apply any preprocessing or augmentation steps to your dataset:

Frequently Asked Questions

Yes! It is free to convert Marmot XML data into the Sagemaker GroundTruth Manifest format on the Roboflow platform.

If you have between a few and a few thousand images, converting data between these formats will be quick. But, the time it takes to convert between data formats increases with the more images you have.
