Dataset Summary

Localized Narratives, a new form of multimodal image annotations connecting vision and language. We ask annotators to describe an image with their voice while simultaneously hovering their mouse over the region they are describing. Since the voice and the mouse pointer are synchronized, we can localize every single word in the description. This dense visual grounding takes the form of a mouse trace segment per word and is unique to our data. We annotated 849k images with Localized Narratives: the whole COCO, Flickr30k, and ADE20K datasets, and 671k images of Open Images, all of which we make publicly available.

As of now, there is only the OpenImages subset, but feel free to contribute the other subset of Localized Narratives!

OpenImages_captions is similar to the OpenImages subset. The differences are that captions are groupped per image (images can have multiple captions). For this subset, timed_caption, traces and voice_recording are not available.

Dataset Structure

Data Instances

Each instance has the following structure:

{
  dataset_id: 'mscoco_val2017',
  image_id: '137576',
  annotator_id: 93,
  caption: 'In this image there are group of cows standing and eating th...',
  timed_caption: [{'utterance': 'In this', 'start_time': 0.0, 'end_time': 0.4}, ...],
  traces: [[{'x': 0.2086, 'y': -0.0533, 't': 0.022}, ...], ...],
  voice_recording: 'coco_val/coco_val_137576_93.ogg'
}

Data Fields

Each line represents one Localized Narrative annotation on one image by one annotator and has the following fields:

• dataset_id: String identifying the dataset and split where the image belongs, e.g. mscoco_val2017.
• image_id String identifier of the image, as specified on each dataset.
• annotator_id Integer number uniquely identifying each annotator.
• caption Image caption as a string of characters.
• timed_caption List of timed utterances, i.e. {utterance, start_time, end_time} where utterance is a word (or group of words) and (start_time, end_time) is the time during which it was spoken, with respect to the start of the recording.
• traces List of trace segments, one between each time the mouse pointer enters the image and goes away from it. Each trace segment is represented as a list of timed points, i.e. {x, y, t}, where x and y are the normalized image coordinates (with origin at the top-left corner of the image) and t is the time in seconds since the start of the recording. Please note that the coordinates can go a bit beyond the image, i.e. <0 or >1, as we recorded the mouse traces including a small band around the image.
• voice_recording Relative URL path with respect to https://storage.googleapis.com/localized-narratives/voice-recordings where to find the voice recording (in OGG format) for that particular image.
