摘要
本文在分析了volume illustration技术中的边界增强基础上,提出了基于变化增强量机制的改进算法,即加入距离因子的边界增强,这种方法会进一步增加体绘制的灵活性。另外,以现有的边界检测技术为基础,提出了添加深度感信息的方法和基于积分融合方式的边界检测方法,使用该融合方式可以通过Z轴超采样改善图像质量。
Based on the analysis of boundary enhancement approaches in volume illustration, improved method with changing enhancement parameters is proposed, namely distance weight boundary enhancement. It is able to increase flexibility of volume rendering further. In addition, an approach of adding depth cues to contour detection is proposed, and an algorithm based on integration composition mode is introduced. With this composition mode, result image quality can be improved through Z-axis super sampling.
