Detailed Features

Class, Attribute, and Track ID filters

Users can filter only the instances they want to check. By checking the same classes and attributes collectively, it is available to speed up the inspection and quickly find incorrect labeling data.

  • classes, attribute filters
    When filtering, classes support single selection, and attributes support multiple selections. When selecting multiple attributes, only the instances that contain all the selected attribute values are exposed.
  • Track ID Filter
    Instances only in the scene file that are set to the same track ID are exposed. The Track ID filter is only activated when loading 'Thumbnail Viewer' for a single scene file in a dataset or studio.

View settings

It is available to set visualization for instance thumbnails.

  • See the points: It shows the points of the instance.
  • Out-of-area opaque: It treats non-instance areas opaque.
  • Original pixelation: Pixels the source file. It is available to make the instance separation area clearer.
  • Line Thickness/Line Opacity: It controls the thickness and opacity of the instance's lines.
  • Outline view: It shows the outlines of the instance.
  • Area opacity: It adjusts the opacity of the instance area.
  • View First Line: When creating an instance, mark the first line drawn as a dotted line.

Use thumbnail size

It is available to use thumbnail sizing to suit your purpose. By increasing the thumbnail size, many instances can be inspected on one screen so that you can increase speed and accuracy. When reducing the size, it is possible to inspect more instances at once, which can improve speed.

Instance Information

It is possible to turn on and off the class and attribute information at the bottom of the instance thumbnail.

Open in studio

By choosing the button next to the file name on the instance card, it is possible to open studio and check what the task content of the file is.
