Spectral Sensitivity Estimation Without a Camera

no code implementations • 23 Apr 2023 • Grigory Solomatov, Derya Akkaynak

As consumer cameras are not designed for high-precision visual tasks, manufacturers do not disclose spectral sensitivities.

SeaThru-NeRF: Neural Radiance Fields in Scattering Media

1 code implementation • CVPR 2023 • Deborah Levy, Amit Peleg, Naama Pearl, Dan Rosenbaum, Derya Akkaynak, Simon Korman, Tali treibitz

Even more excitingly, we can render clear views of these scenes, removing the medium between the camera and the scene and reconstructing the appearance and depth of far objects, which are severely occluded by the medium.

Sea-Thru: A Method for Removing Water From Underwater Images

2 code implementations • CVPR 2019 • Derya Akkaynak, Tali Treibitz

Robust recovery of lost colors in underwater images remains a challenging problem.

A Revised Underwater Image Formation Model

no code implementations • CVPR 2018 • Derya Akkaynak, Tali treibitz

The current underwater image formation model descends from atmospheric dehazing equations where attenuation is a weak function of wavelength.
