Exports
We dive into exports and explain how to export in JSON, COCO, VOC and more, with Darwin.py.
In this Darwin Fundamentals session, we tackle Exports and outline the step-by-step process to leveraging Exports within Darwin. Ready for something a bit more detailed? Head to our Darwin Advanced session on Exports.
Darwin Users can leverage the dataset versioning model, which is a powerful tool for managing and exporting datasets in 2D computer vision projects. This tutorial begins with an explanation of how to navigate to the export function, how to create a dataset version, and the formats available for version formats (including JSON, COCO, VOC, and more).
The tutorial also goes into detail on filters you can apply to your Exports, including exporting based on annotation class, annotator/reviewer metadata, and exporting explicitly selected images.
Finally, we touch on some of the collaborative opportunities that can come with Exports, such as the Export Token - which gives permission to anyone with the export file, regardless of whether they have a V7 account or not, to download the corresponding image for each annotation.
For products seeking FDA or HIPAA compliance, you’ll need to be particularly mindful of how you approach Exports. You can read more about V7’s commitment to security standards here, and dive into detail of our approach to FDA compliance here.
With this tutorial, you’ll come away with a clear understanding of how to handle Exports - whether you’re tackling research or creating FDA-focused solutions. For those looking to go a little further, developers and data scientists can also explore our Darwin documentation, which includes commands for listing and downloading Exports.
Press the export button on the top right to bring up the dataset versioning model. This will list all the available export versions for this dataset. You can download any of these locally or click on a version name to copy a CLI command to your clipboard. If you're new to Darwin, you probably haven't created one yet, so let's make one.
Start by giving it a name and then we'll pick a format. Darwin supports many of these like popular formats like Coco XML formats from inferior labeling tools like C V A T. A versatile Darwin JS format that resembles the coco format with se added features, a Darwin xml Pascal VAK for the old school, as well as semantic masks and p and g and instance masks following the open images standard.
By default, Darwin will only prompt you to export completed images, but you can also choose selected images to export images that may be incomplete or perhaps archived. You can also add class filters to exports. For example, only export the car class and leave out any others. You can choose to include annotator metadata to the export files, which will include the first name, last name, and username of the people who created the labels in this data set.
This means each label with an adjacent or XML file will have a named author. This is very important if you're working in the medical field, for example, and want to seek F D a approval for your algorithms one day. Finally, you can add an export token to each export file. This will allow anyone with the export file, whether they have an account with V seven or not, to download the image that corresponds to each annotation.
This is very useful if you're collaborating with external parties or when to publish your data set. However, this will leave your images unencrypted, so do not select this option if you need to abide to encryption rules such as HIPAAs. All of these export versions are also available within open data sets.
You can make a data set open from the setting tab, and it's a great way to share your research with the world and give any visitor a graphical user interface to browse and filter your data set. For developers and data scientists, there is a lot more that you can do with Darwin exports by visiting the Darwin PI documentation, there are commands to list exports.
Download them locally. As well as bindings for PyTorch to load data into Torch Vision or detect run two. Make sure to give those a look. And don't forget to star us on GitHub.
