Data Fields

• image : the image id
• image : PIL.Image.Image object containing the image. Note that when accessing the image column: dataset[0]["image"] the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the "image" column, i.e. dataset[0]["image"] should always be preferred over dataset["image"][0]
• width : the image width
• height : the image height
• objects : a dictionary containing bounding box metadata for the objects present on the image
  • id : the annotation id
  • area : the area of the bounding box
  • bbox : the object's bounding box (in the coco format)
  • category : the object's category.
