| 目的 把视觉感兴趣区域概念引入直方图的建造中,提出了一种新的基于视觉感兴趣区域的图像增强方法,使增强效果更符合人眼视觉感知。 方法 首先在标准观测环境下利用先进的眼动仪设备获得人眼感兴趣区域,然后计算各子区域的平均显著值,以确定各个子区域的权重系数,最后采取类似直方图均衡化的思想,优化配比灰度级的动态范围。 结果 通过主客观实验结果表明,增强后的图像更符合人眼视觉感知。 结论 结合了视觉感知特性的直方图增强方法,弥补了传统直方图与人眼视觉感知不一致的弊端,其增强效果更佳。 |

| Objective The concept of visual region of interest was brought into the construction of the histogram. We proposed a new visual image enhancement method based on region of interest, in order to make the enhanced images more in line with the visual perception of the human eye. Methods In this method, advanced eye tracker device was used in the standard observation environment and visual region of interest, namely the human saliency map was obtained, whereby the image of the significant regions was analyzed. In each sub-region, salient value was obtained and normalized, so that weighted coefficient was obtained for each sub-region. Finally a similar idea to histogram equalization was adopted to optimize the dynamic range of the ratio of gray levels. Results Through subjective and objective experiments, the experimental results showed that the enhanced images were more in line with the visual perception of the human eye. Conclusion Histogram enhancement method combined with perceptual characteristics could compensate the drawback of the traditional histogram in the inconsistency with the visual perception, resulting in more enhanced image. |
