Abstract

The purpose of this study is focusing on “Analysis for human’s Region of Interest (ROI) on complex images”, and collected the subject’s eye movement and ‘scan path’ when assessing perceptual image quality task by using eye tracking method. The participants in this study were 30 students with convenience sampling from design, management and engineering college in National Yunlin University of Science and Technology. 11 stimulus of this experiment was selected from ISO standard image by focus group, and the type of image was divided into still image, portrait, landscape and architecturally image. The two tasks in this experiment are ‘assessing perceptual image quality’ and ‘assessing perceptual color quality’. And analysis the ‘Fixation duration’ and ‘Amplitude of saccade’ of ROIs from eye movement when assessing perceptual image quality task. The results show 1. when the ‘perceptual color quality’ is higher and the ‘perceptual image quality’ is higher, too; 2. The subjects were tended to browse the still and landscape image widely when assess the perceptual image quality and perceptual color quality task; 3. In contrast to the still image, the subjects were focus on the face of portrait image; 4. The subjects’ eye movement was tended to stabilize and homogenize when assess the ‘perceptual color quality task’.
