| Outline of Final Research Achievements |
It is commonly believed that by drawing viewer's attention to particular objects, people with color vision deficiency activity can be effectively facilitated. The aim of our research is to propose a image modification method for directing viewer's gaze to specific regions of interest, using a novel saliency map model based on Lab color space. First, we compute the saliency map for people with color vision deficiency, and modify the Lab components based on the obtained saliency map for adjusting saliency value. And then, we repeat this process until the specified region has become the most salient. With the image obtained in this way, we can smoothly attract the viewer's attention to the specific region, without any interruption to the viewer's gaze. We performed a gaze-measurement and a subjective experiment. As a result, we confirmed that the viewer's visual attention is indeed attracted toward our specific region without uncomfortable feeling.
