| 摘 要： | 提出一种高动态范围体数据传递函数设计方法。该方法运用高动态范围图像领域色调映射算法(TMO)的原理,基于数据集的全局直方图统计,实现高动态范围数据集的有效压缩,使得绘制图像呈现更多的数据细节实验结果表明,这种基于TMO的传递函数能够更好的显示体数据的内部细节。

| Abstract: | A novel transfer function design method for high dynamic volume data is presented. Based on dataset＇s global histogram, efficient compression is implemented by a tone mapping operator （TMO） for the maps high dynamic range data in order to provide more data details for the eolormap. Experimental results show that much more detailsin volume data is presented by the rendering images. |
