DATA Information

About

All annotations are based off COCO+LVIS and we provide annotations for: clicks, scribbles, loose lassos, tight lassos, and rectangles. Our final dataset consists of a: training set with 99,161 images, 857,669 regions, 186,740 region parts, and 12,839,936 samples; validation set with 3,318 images, 32,938 regions, 5698 region parts, and 413,784 samples; and test set with 1,423 images, 11,703 regions, 2417 region parts, and 246,080 samples. Of the 246,080 samples in the test set, 69,852 samples belong to the scenario of multi-region segmentation.

Supported Gestures

We provide support for 5 different gesture types indexed in the range [0,4].

{
  0: 'click',
  1: 'scribble',
  2: 'loose lasso',
  3: 'tight lasso',
  4: 'rectangle'
}

JSON Structure

While we provide code to simplify the loading of DIG data, we provide further metadata in the JSON files. All annotations/GTs/previous segmentations are stored in RLE format.

  • img_id: Prefix of image/gt in COCO+LVIS. e.g., IMG_ID.jpg/IMG_ID.png.
  • size: Dimensions of the sample.
  • mul_obj_id: Object ID in original ground truth for multi-region selection setting. [TEST ONLY]
  • obj_id: Object ID in original ground truth.
  • syn_gt: Valid pixels for synthetic (local) GT.
  • syn_gt_void: Void pixels for synthetic (local) GT. Value is 255.
  • syn_annotations: Multi-gesture annotations.
  • has_prior: Boolean value indicated that a sample at index i has a previous segmentation.
  • prior: Previous segmentation.
  • corr_id: Which correction the prior and annotation correspond to.
  • gesture: What type of gesture. Ranges from [0,4].
  • mode: If the gesture indicates content to be added or removed.
  • has_mul: Indicates if a sample at index i has multi-region annotations. [TEST ONLY].
  • mul_gesture: Gesture for multi-region setting. [TEST ONLY].
  • mul_gt: GT for multi-region setting, no void pixels. [TEST ONLY].
  • mul_annot: Gesture annotation for multi-region setting. [TEST ONLY].
  • mul_prior: Previous segmentation for multi-region setting. [TEST ONLY].
