Dataset Description

NOTE: This dataset is an unofficial port of small NORB based on a repo from Andrea Palazzi using this script. For complete and accurate information, we highly recommend visiting the dataset's original homepage.

Dataset Summary

From the dataset's homepage:

This database is intended for experiments in 3D object reocgnition from shape. It contains images of 50 toys belonging to 5 generic categories: four-legged animals, human figures, airplanes, trucks, and cars. The objects were imaged by two cameras under 6 lighting conditions, 9 elevations (30 to 70 degrees every 5 degrees), and 18 azimuths (0 to 340 every 20 degrees).

The training set is composed of 5 instances of each category (instances 4, 6, 7, 8 and 9), and the test set of the remaining 5 instances (instances 0, 1, 2, 3, and 5).

}

Data Fields

Explanation of this dataset's fields:

  • image_lt: a PIL image of an object from the dataset taken with one of two cameras
  • image_rt: a PIL image of an object from the dataset taken with one of two cameras
  • category: the category of the object shown in the images
  • instance: the instance of the category of the object shown in the images
  • elevation: the label of the elevation of the cameras used in capturing a picture of the object
  • azimuth: the label of the azimuth of the cameras used in capturing a picture of the object
  • lighting: the label of the lighting condition used in capturing a picture of the object

For more information on what these categories and labels pertain to, please see Dataset Summary or the repo used in processing the dataset.
