After you've uploaded images to LandingLens, you can label them. Labeling images is an important step of the model creation process. The labels you provide on images are called ground truth. When your model trains, it learns to detect objects of interest by referring to the ground truth, so it's important that your labels are accurate and consistent.

For more information on labeling images using specific labeling tools, refer to the relevant article based on your project type:

Tip:
Create a label book to establish clear labeling guidelines and provide proper training to help labelers understand your project's requirements.

Remove Labels From Images

In LandingLens, there are multiple ways to remove labels from images. For example, you can quickly remove all labels from an image and then relabel it. Or, you can mark an image as "No Class" to remove all labels from that image.

Caution:
You cannot undo removing labels. However, you can create a snapshot of your data as a backup, and then remove labels. If you later decide you want the labels, you can restore the snapshot. For more information on dataset snapshots, go here.
