Image Annotations

Here we show side-by-side comparisons of our Mechanical Turk-based ground truth annotations and our saliency-based heuristic annotations. To compute ground truth, we score each line based on the percentage of worker annotations that included that line. Lines with scores over 40% are included in the ground truth annotations. To compute the heuristic annotation, we do a weighted sum of saliency scores near each line. Lines with the top three scores are selected for the annotation, see paper for details.
