Simultaneous temperature estimation and nonuniformity correction from multiple frames

no code implementations23 Jul 2023 Navot Oz, Omri Berman, Nir Sochen, David Mendelovich, Iftach Klapp

We also propose a novel offset block that incorporates the ambient temperature into the model and enables us to estimate the offset of the camera, which is a key factor in temperature estimation.

Estimating temperatures with low-cost infrared cameras using deep neural networks

no code implementations22 Jul 2023 Navot Oz, Nir Sochen, David Mendelovich, Iftach Klapp

The neural network was trained with the simulated nonuniformity data to estimate the object's temperature and correct the nonuniformity, using only a single image and the ambient temperature measured by the camera itself.

A note on the variation of geometric functionals

no code implementations20 Jul 2022 Nir Sochen

The aim of this note is to point to the correct way to derive the EL and the gradient descent equations such that the resulted gradient descent equation is geometric and makes sense.

Deep Learning Solution of the Eigenvalue Problem for Differential Operators

no code implementations1 Jan 2021 Ido Ben-Shaul, Leah Bar, Nir Sochen

Solving the eigenvalue problem for differential operators is a common problem in many scientific fields.

Solving the functional Eigen-Problem using Neural Networks

no code implementations20 Jul 2020 Ido Ben-Shaul, Leah Bar, Nir Sochen

In this work, we explore the ability of NN (Neural Networks) to serve as a tool for finding eigen-pairs of ordinary differential equations.
