PDRF: Progressively Deblurring Radiance Field for Fast and Robust Scene Reconstruction from Blurry Images

Posted by klaurent August 17, 2022August 30, 2022UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Rama Chellappa, , , | Summary: We present Progressively Deblurring Radiance Field (PDRF), a novel approach to efficiently reconstruct high quality radiance fields from blurry images. While current State-of-The-Art (SoTA) scene reconstruction methods achieve photo-realistic rendering results from clean source views, their performances suffer when […]

Super-Resonant Dark Matter

Posted by klaurent August 16, 2022August 30, 2022Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Yonit Hochberg, Eric Kuflik, Kevin Langhoff | Summary: We introduce Super-Resonant Dark Matter, a model of self-interacting dark matter based on the low energy effective theory of supersymmetric QCD. The structure of the theory ensures a resonant enhancement of the self-interactions of the […]
