Abstract
In order to develop a visual attention model for quantifying effects of object size, we made a hypothesis that the visual attention by object size of rectangle can be quantified by the width and height of object. To verify the hypothesis, we carried out an experiment with 18 participants. As a result of the experiment, we found that width, height, and interaction between them are effective factors for quantifying the visual attention by object size. From the comparison of estimation accuracy with the existing model based on pixel level position, we found that the proposed model based on the width and height of object has an equivalent estimation accuracy to the existing model. We concluded therefore that the visual attention by object size of a rectangle can be quantified by the width and height of object.
