摘要
提出的自适应HDR图像可视化算法中,输入图像被分解为基本层和细节层。该算法将整体明暗效果的显示看做整体问题,对表示亮度的基本层采用基于整体统计信息的直方图调整算法处理;可视细节信息的保持作为局部问题,算法采用自适应细节增强算法处理细节层。通过定义映射图对细节增强后的图像进行最终映射,将两方面结合起来得到最终结果。实验结果表明,该算法能对HDR图像进行较高视觉质量的显示。
High dynamic range （HDR） image is designed to depict the full visual dynamic range of the real-world scenes. A visualization algorithm was necessary when displaying HDR images on the standard output devices. A novel algorithm based on spatial and statistical information was proposed for the display of HDR images. The algorithm could deal with the problems of overall impression preservation and visual details reproduction. The trade-off between these two issues could be achieved a balance through the adaptive enhancement of details. Experimental results show the superior performance of the approach in terms of visual quality.
