Polygon Labeling

Many labeling tasks can be handled well with bounding box labels, but in cases where you need a more precise way to annotate object, polygon labels are an excellent option. Polygon labels allow you to identify and annotate the exact pixels of your image that represent the object that you would like to label. Polygon labels will output a sequence of x, y coordinates for every point that comprises the polygon.

First you will need to select "Polygons" as the task type when creating your labeling task.

Select "Polygons" as your task type when creating a new labeling task

When labeling your images, you will be able to create multi-point shapes that can outline the precise pixels of the object that you would like to label. Just remember that you will need to "connect the dots" by connecting the last point in your polygon with the first point.

Outline your image and be sure to connect the first and last nodes of your polygon

Video

Scribe provides powerful tools for labeling video. When working with video, you can leverage video interpolation tools to quickly label thousands of individual frames of video. This rapid labeling technique makes video an excellent source of training data, even if you want your model to primarily analyze still images. You can QuickTrain and DeepTrain models on video data that has been labeled in Scribe.

Interpolation

Interpolation allows you to quickly label multiple frames of video with the same concept. Simply select the interpolation icon and draw a bounding box around the object that you would like to label. Then scrub the video player to a new point in the video and move and adjust the bounding box to the new location of the object. Interpolation will automatically draw a series of bounding boxes between them and a keyframe marker will identify the point in the video where a new interpolation begins.

Video Keyboard shortcuts

  • Q - Start of video

  • W - Scrub backward

  • E - Scrub forward

  • R - End of video

Text

Scribe makes it easy to label your text data. You can review text inputs in the same view that you would review images for classification tasks.

Editing Labels

You can easily resize, move, or relabel existing bounding boxes. Just click on the bounding box that you would like to change and drag to move or resize. Bounding boxes can be relabeled by clicking the "edit" icon next to the existing label in the right hand sidebar.
