ViewCrafter: Taming Video Diffusion Models for High-fidelity Novel View Synthesis

IEEE Transactions on Pattern Analysis and Machine Intelligence
Despite recent advancements in neural 3D reconstruction, the dependence on dense multi-view captures restricts their broader applicability. In this work, we propose ViewCrafter, a novel method for synthesizing high-fidelity novel views from single or ...

Learning High Fidelity Depths of Dressed Humans by Watching Social Media Dance Videos

Computer Vision and Pattern Recognition, 2021
A key challenge of learning the geometry of dressed humans lies in the limited availability of the ground truth data (e.g., 3D scanned models), which results in the performance degradation of 3D human reconstruction when applying to real-world imagery ...

Hi3dgen: High-Fidelity 3D Geometry Generation From Images Via Normal Bridging

IEEE International Conference on Computer Vision
With the growing demand for high-fidelity 3D models from 2D images, existing methods still face significant challenges in accurately reproducing fine-grained geometric details due to limitations in domain gaps and inherent ambiguities in RGB images.

Decreased Fidelity in Replicating CpG Methylation Patterns in Cancer Cells

Cancer Research, 2005
Abstract The unmethylated or methylated status of individual CpG sites is faithfully copied into daughter cells. Here, we analyzed the fidelity in replicating their methylation statuses in cancer cells. A single cell was clonally expanded, and methylation statuses of individual CpG sites were determined for an average of 12.5 DNA ...

High Fidelity MMI Excitation Patterns for Optofluidic Multiplexing

Conference on Lasers and Electro-Optics, 2018
High fidelity interference patterns from multimode interference waveguides are needed for multiplexed optofluidic biosensors. Spot pattern fidelity can be optimized by careful design of the single-mode waveguides used to excite the multimode waveguides.

School fidelity in fishes: The yellow perch pattern

Animal Behaviour, 1984
School fidelity concerns the cohesiveness of social aggregations over time, as measured by the regularity or repeatability with which known individuals re-occur as members of a school. School fidelity was measured by divers who observed yellow perch (Perca flavescens) marked with individually recognizable tags in Cazenovia Lake, New York.

Pattern fidelity in nanoimprinted films using CD-SAXS

SPIE Proceedings, 2005
The primary measure of process quality in nanoimprint lithography (NIL) is the fidelity of pattern transfer, comparing the dimensions of the imprinted pattern to those of the mold. As a potential next generation lithography, NIL is capable of true nanofabrication, producing patterns of sub-10 nm dimensions. Routine production of nanoscale patterns will
