Objectdex

About Objectdex

Objectdex is a dataset built upon the annotations of the SUN Database. Starting from a set of scenes (scenes universe), the objects appearing in them are extracted. They are filtered and reorganised, each provided with the relative scene distribution.

The dataset is represented as an intuitive json file. For instance, the clothes entry is represented as follows:

  {
    "object_name": "clothes",
    "distribution": [
      {
        "scene_name": "bedroom",
        "count": 7,
        "percentage": 0.6363636363636364
      },
      {
        "scene_name": "garage",
        "count": 3,
        "percentage": 0.2727272727272727
      },
      {
        "scene_name": "nursery",
        "count": 1,
        "percentage": 0.09090909090909091
      }
    ]
  }

This dataset can be employed for the scene recognition task.
