These are the currently ongoing annotation projects. Those that will be derelicted or archived are those with the dev- prefix.

Click on one of the projects. For the purposes of this tutorial, we will go with the one labelled ns-ii-rbp-ct-llbn-20230403-20230519.

Step 2: Create a Task

To create a new task, click on the blue + icon as seen below.

Create task

A new interface like below will show up.

New Task

Let’s say your task name is endangered_crocodile_a5763f22_animal and belongs to the ns-ii-rbp-ct-llbn-20230403-20230519 project folder (your supervisor will detail the tasks to be created).

You will place the name endangered_crocodile_a5763f22_animal on the Name dialog box.

Leave the project name as is because it belongs to the ns-ii-rbp-ct-llbn-20230403-20230519 project.

Place your inputs as shown below:

CVAT inputs

Since the suffix of our task name ends with _animal, we shall go to the Connected file share and select the md_processed link, like so.

Task to be processed

In the search bar, enter the endangered_crocodile_a5763f22 without the _animal suffix.

Click on the name that appears.

A new interface will appear but select the animal checkbox since our task name is ending with _animal and is an animal anyway!

The task

Click Submit && Continue.

After clicking the Submit && Continue button, the CVAT platform will load for a while but it’s important to wait until the process is complete.

If you go back to the ns-ii-rbp-ct-llbn-20230403-20230519 project page, the task name should appear there. It should read 1-annotating, 1-total but the progress bar is greyed out. Below is just an example of a completed task.

Step 3: Provide the annotation files

To provide the annotation files, click Open on the task name. The task interface will appear.

Task interface

Your supervisor will provide the necessary annotation files. To upload them into the task, click on the Actions>Upload annotations button.

Import annotations

Unless otherwise indicated, the format will always be CVAT 1.1.

Use the click or drag mini-interface to locate the respective annotations .xml file from your local computer. Click ok when you find it. A message will appear saying that current annotations will be lost. Just click ok.

A new message will appear at the top right saying that the annotation import has started. Better wait until the process is complete.

Once the process completes, a message such as Annotation x has been loaded to task x will appear at the top right.
