Exporting annotations

Guide on how to export completed annotations in various formats like COCO and YOLO on the Mindkosh Annotation platform

Mindkosh supports a variety of annotation formats when exporting the completed annotations. To export annotations from a task, create a Release. You can manage Releases from the Release tab on the task page.

The release page shows you a list of all the releases created earlier. If you want to download a previously exported set of annotations, you can do so from here.

To create a new release, click on the "Create new release button", which will take you to the New release page. Once on that page, select the batches you would like to export, and click on on Create release. This will open up the format selection dialog box.

Choosing an annotation format for export

Choose the format you would like to export in. Do note that not all formats support all types of annotations. For example, the YOLO format only supports bounding box annotations. If you have polygons in your task, those will not be included in the YOLO export.

Optionally, you can also add a description to keep track of the releases. You can also use the description to add a version system to your exports, as shown in the image above.

Supported formats for Image annotation

1. COCO

2. Pascal VOC

3. YOLO - Bounding boxes only

4. CVAT for images

5. CVAT for Video - Applicable to videos only

6. Datumaro

7. Segmentation Mask - Single channel PNG masks for semantic and instance segmentation

8. TFRecord

Supported format for point cloud annotation

As of now, only Mindkosh format is supported when exporting point cloud annotations. Details of the format can be found here. Annotations in the Mindkosh format can be converted to others like KITTI using the Python SDK. For other formats, get in touch with us, and our team would be happy to assist you.

Downloading the annotations

Creating a release can take some time depending on the volume of data and the type of annotation involved. You can see the status of the release on the Releases page. Once the annotations are ready for download, the status will change to "Ready". You will also get a notification indicating the release is ready for download. You can then download the release by clicking on the download button for that release.

Please note that you can only maintain 10 releases at any time. Once you have reached that limit, you will need to delete a release, in order to create a new one.
