EfficientDreamer: High-Fidelity and Robust 3D Creation via Orthogonal-view Diffusion Prior

1 code implementation25 Aug 2023 Zhipeng Hu, Minda Zhao, Chaoyi Zhao, Xinyue Liang, Lincheng Li, Zeng Zhao, Changjie Fan, Xiaowei Zhou, Xin Yu

This limitation leads to the Janus problem, where multi-faced 3D models are generated under the guidance of such diffusion models.

Towards Unbiased Volume Rendering of Neural Implicit Surfaces With Geometry Priors

no code implementations CVPR 2023 Yongqiang Zhang, Zhipeng Hu, Haoqian Wu, Minda Zhao, Lincheng Li, Zhengxia Zou, Changjie Fan

In this paper, we argue that this limited accuracy is due to the bias of their volume rendering strategies, especially when the viewing direction is close to be tangent to the surface.

Stochastic Steffensen method

no code implementations28 Nov 2022 Minda Zhao, Zehua Lai, Lek-Heng Lim

Is it possible for a first-order method, i. e., only first derivatives allowed, to be quadratically convergent?

Stochastic Optimization

Adaptively Meshed Video Stabilization

no code implementations14 Jun 2020 Minda Zhao, Qiang Ling

Moreover, foreground and background feature trajectories are no longer distinguished and both contribute to the estimation of the camera motion in the proposed optimization problem, which yields better estimation performance than previous works, particularly in challenging videos with large foreground objects or strong parallax.
