A study on visibility model considering visual characteristics

点击翻译按钮获取中文摘要

The visibility was evaluated using the methods of psychological estimation and physiological estimation, and the predictive model of visibility is proposed. In the psychological estimation, the visibility of the elderly and dichromatic vision was measured using the simulation filters, and the predictive model of visibility was proposed using results of the paired comparison. In the physiological estimation, it was shown that the difference of contrast influences the cognitive judgment by the silent reading time, the gaze duration and the saccade calculated from point-of-regard measurement.
