Annotating images

To assign classes to the unclassified images click on the Annotate button. You can choose between "Grid Annotation" and "Detail Annotation"

Detail Annotation

First choose Detail Annotation.

You are redirected to another page where an "annotation job" has been created.

Annotation jobs

To structure the annotation work an annotation job holds all the data of a domain when it is created. You can send the link to a colleague to help with annotation (see Collaboration), multiple people can work on an annotation job at the same time.

There are predefined hotkeys which will make it faster to annotate the images.

By pressing the a, s or d key you can select which type of nut is shown on the image.

Review or change the hotkeys

Click on the burger menu in the annotation job and select "Show Annotation Job instructions" to see the hotkeys. Click on the edit icon next to the Automatic Hotkey Set to review or change the hotkeys.

Press Enter to save the image and go on to the next one.

On the bottom you can see how many images are left to do.

Note, that you have been redirected to the advanced data handling service which is shown in a separate window. You can see a lot of options on the left panel, but you can ignore those for now.

The underlying dStudio data handling service provides many useful options to further structure data for example:

• Sharing data with colleagues
• Annotating data with metadata, like the source of the data
• Filtering data and creating snapshots of subsets of the data

For more information please complete the extended tutorials.

Annotate a few images, then click on the "Open in dStudio" button in the navigation side panel to return to the Domains page in dStudio. You can see now, the images are sorted in their respective classes.

You can return at any time to the annotationjob by choosing the Detail Annotation again.

Grid Annotation

Click again on the "Annotate" button, but choose "Grid Annotation". You will be redirected to an annotation job where you can see a lot of images at once. You have the same hotkeys as before, but now you can select images that belong to one or the other class. Select a class via hotkey or by clicking on it. Then select the images that apply to this class.

You can also give all images the same class by using the check all button (double checkmark).

This makes sense if you have a lot of the same images on one page

Depending on the ratio of you images (landscape or vertical) it may make more sense to have a 3x5 grid instead of a 5x3. You can change the ratio in the menu

Annotate images later

If you want to skip images, because it is not clear what is displayed on the image you can choose to annotate it later.

In the detail annotation job click on the "Annotate Later" button next to the save button. They will be moved to the "Annotate Later Queue", which you can see when clicking on the menu and selecting "Annotate later queue". When you save annotations in the "Annotate Later Queue" they are moved back to the main queue.

In the grid annotation job click select "Annotate Later" and mark the images you want to annotate later. They get a red border. You will see a popup, that warns you that one or multiple annotations are missing. Click "Skip missing" to move the images to the Annotate later queue.
