Labeling

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.

Label Images

To label images:

1. Click to open the image you want to label.
2. Perform one of the following actions:
   1. If the image has no objects of interest to detect, click the No Class button. LandingLens marks the image as No Class.Mark the Image as "No Class" When There Are No Objects of Interest
   2. Use the provided labeling tools to label the object of interest. LandingLens automatically saves the label.

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 if you want to remove all labels. For more information on dataset snapshots, go here.

Let's say you accidentally labeled an image, but there are no objects to detect in that image. You can quickly remove those labels and mark the image as No Class. To do this:

1. Click to open the image you want to edit.
2. Click the No Class button.
   
   Click "No Class" to Remove Labels and Mark the Image as "No Class"
