Learned 3D volumetric recovery of clouds and its uncertainty for climate analysis

no code implementations9 Mar 2024 Roi Ronen, Ilan Koren, Aviad Levis, Eshkol Eytan, Vadim Holodovsky, Yoav Y. Schechner

We demonstrate the approach in simulations and on real-world data, and indicate the relevance of 3D recovery and uncertainty to precipitation and renewable energy.

GRAM: Global Reasoning for Multi-Page VQA

no code implementations7 Jan 2024 Tsachi Blau, Sharon Fogel, Roi Ronen, Alona Golts, Roy Ganz, Elad Ben Avraham, Aviad Aberdam, Shahar Tsiper, Ron Litman

The increasing use of transformer-based large language models brings forward the challenge of processing long sequences.

Complex-valued Retrievals From Noisy Images Using Diffusion Models

no code implementations6 Dec 2022 Nadav Torem, Roi Ronen, Yoav Y. Schechner, Michael Elad

In this study, we generalize annealed Langevin Dynamics, a type of DDM, to tackle the fundamental challenges in optical imaging of complex-valued objects (and real images) affected by Poisson noise.

GLASS: Global to Local Attention for Scene-Text Spotting

2 code implementations5 Aug 2022 Roi Ronen, Shahar Tsiper, Oron Anschel, Inbal Lavi, Amir Markovitz, R. Manmatha

In recent years, the dominant paradigm for text spotting is to combine the tasks of text detection and recognition into a single end-to-end framework.

4D Cloud Scattering Tomography

1 code implementation ICCV 2021 Roi Ronen, Yoav Y. Schechner, Eshkol Eytan

We derive computed tomography (CT) of a time-varying volumetric scattering object, using a small number of moving cameras.
