Eliciting Perceptual Ground Truth for Image Segmentation
[chapter]
2006
Lecture Notes in Computer Science
Preserved Fulltext
In this paper, we investigate human visual perception and establish a body of ground truth data elicited from human visual studies. ...
These rankings were then used to score the perceptions, identify the preferred human breakdowns and thus allow us to induce perceptual rules for human decomposition of figurative images. ...
These ground truth images may be further analysed to elicit statistics and preference scores regarding the decomposition preferences of humans: i.e., which decomposition is generally preferred for each ...

We previously investigated human visual perception of trademark images and established a body of ground truth data in the form of trademark images and their respective human segmentations. ...
The work indicated that there is a core set of segmentations for each image that people perceive. ...
This core set of segmentations forms the ground truth for our evaluations into inducing a perceptual relevance classifier. ...
