Instantiation-Net: 3D Mesh Reconstruction from Single 2D Image for Right Ventricle

no code implementations16 Sep 2019 Zhao-Yang Wang, Xiao-Yun Zhou, Peichao Li, Celia Riga, Guang-Zhong Yang

3D shape instantiation which reconstructs the 3D shape of a target from limited 2D images or projections is an emerging technique for surgical intervention.

U-Net Training with Instance-Layer Normalization

no code implementations21 Aug 2019 Xiao-Yun Zhou, Peichao Li, Zhao-Yang Wang, Guang-Zhong Yang

However, two potential issues exist in BIN: first, the Clip function is not differentiable at input values of 0 and 1; second, the combined feature map is not with a normalized distribution which is harmful for signal propagation in DCNN.

One-stage Shape Instantiation from a Single 2D Image to 3D Point Cloud

no code implementations24 Jul 2019 Xiao-Yun Zhou, Zhao-Yang Wang, Peichao Li, Jian-Qing Zheng, Guang-Zhong Yang

An average point cloud-to-point cloud (PC-to-PC) error of 1. 72mm has been achieved, which is comparable to the PLSR-based (1. 42mm) and KPLSR-based (1. 31mm) two-stage shape instantiation algorithm.
