具体而言,SelfOcc首先使用解码器将3D表示解码为符号距离场(SDF)。SDF提供了一种描述物体表面的有效方式,其中每个点的值表示该点到最近表面的距离,正负号表示点在物体内部还是外部。相较于密度场,SDF具有更加明确的物理意义和关于梯度大小的约束,从而使其在进行正则化和优化时更加高效。此外,SDF的另一个优点是其在处...
5 验证DC/AC patterns的正确性和电路的正确性 6 使用SDF,验证DC/ACpatterns相关电路的时序是否满足要求 7 使用DC/AC patterns (wgl文件)转换成ATE所需格式,在ATE上调试和使用 所以,OCC电路实现了在shift阶段和capture阶段对时钟(PLL/ATE)进行选择的功能。有两种方式可以插入OCC电路: 1. DFT Compiler自动插入。2....
通过2个MLP将体特征V转换为SDF' 表示: softplus 确保密度值不会变为负值,经过优化后,SDF' 可以直接转换为3D占用结果。 σ 过滤掉占用的体素,并根据 S 确定它们的语义类别。SDF'转3D占用的表达如下: 每个体素单元的表达形式 渲染表达公式 公式定义基本就是Nerf那一套离散化公式, 深度的渲染zk没有MLP, 具体看代...

Acoustic radiation force impulse elastography showed median high shear wave velocities (case 1, 2.75 m/s; case 2, 2.58 m/s) that normalized after specific treatment for sinusoidal obstructive syndrome; therefore, ARFI elastography provided quantitative information that helped diagnose this condition as...
