摘要
在体绘制中引入人工智能技术,实现了转换函数的智能设计和视点的自动选择.该方法把寻找最佳转换函数和视点问题转化为全局优化问题,由初始样本集开始,经过多次迭代和评价逐步得到理想的结果.最后,结合实例给出了转换函数设计的中间图像和视点选择的效果图,显示用户感兴趣的重点部分,并确定对象的最佳观察位置.
A novel intelligent volume visualization method is proposed in the paper. The method introduces artificial intelligent techniques into the design of transfer function and viewpoint selection. By the method, the search for the transfer function and the optimal viewpoint are reformulated as a global optimization problem, to reduce the reluctant computations and interactions. And the image sequence focuses on the interesting part and displays the objects on the optimal position.
