Classification labels¶

To support classification projects, Robovision AI allows adding a classification label to an image, a batch of images, or use the Prediction tool to speed up the process of creating labels.

Classification labels can be used for the following project types:

• Image classification: Involves assigning one label (class) to an image.
• Multilabel image classification: Allows assigning more than one label to an image.

To label with a classification label¶

1. In the Projects module, click the necessary project.

2. In the Label center section, select the needed import or click the right-arrow button ().

   

   The data opens in the label center. You can label images in one of the views—single, thumbnails, or list. To switch the view, click the corresponding button.

   

3. For labeling in the thumbnails or list view, select the samples belonging to the same class:

   • In the thumbnails view, you can select multiple samples by dragging over them. Alternatively, you can hold the Ctrl/Cmd key and select the necessary samples.
   • In the list view, select the checkboxes next to the necessary samples.

   You can also hold the Shift key and select the first and last samples.

   Note

   If you select samples and then go to another page, these samples will no longer be selected.

4. In the left panel, in the Classes section, select the necessary class.

   Image classification: Alternatively, you can assign classes by typing.

   The label is assigned to the sample. Note that members with the Labeler role can view only their own labels or labels generated by the Prediction tool.

5. Multilabel image classification: Select more classes if needed.

6. Multilabel image classification: After you select all necessary classes, to clear the selection in the thumbnails or list view, click Submit.

   Warning

   If you relabel 100+ samples in bulk, you can only replace the existing labels with the ones you have just added. To replace the labels for the selected samples, click Replace. Note that there is no way to recover the labels that got replaced.

To navigate between samples, use one of the following:

• In the single view, use the arrow buttons on the bottom toolbar to navigate between samples or specify the number of the sample you want to open.

• In the thumbnails and list views, you can view a maximum of 100 samples per page:

  • Use the Status panel on the left to navigate between the 100 samples on the page. You can also get the overview of the labeled and unlabeled samples within the page. The labeled samples are marked with green or blue, while unlabeled – with gray. Green indicates that the sample is annotated by the logged-in user, while blue indicates that the annotation comes from another user or is generated by the Prediction tool.
  • Use the arrow buttons on the bottom toolbar to navigate between pages or specify the number of the page you want to open.
