Research interests

We are involved in two space missions: CloudCT: a space mission to probe small clouds using 3D optical scattering tomography that will run on images taken by a large orbiting formation of nano-satellites. It will seek better understanding of clouds and climate, while pushing computational photgraphy and space-enginering technologies to new frontiers. PIs Yoav Schechner (Technion), Ilan Koren (WIS) and Klaus Schilling (ZfT). The CIEL Space Mission is selected to be the next Israeli-French (ISA-CNES) mission. Our group is in the core science team. Our role is to devise measuerements of dynamic 3D flow fields on cloud-tops, from observation satellites that we characterise. Wanted: Students to join this exciting research breakthrough, having interest in any of the following: computer vision, optics, image processing, meteorology, climate.

Resulting studies include:

Tomographic atmospheric recovery; refractive distortions (virtual periscope); imaging through turbid (scattering) media e.g., overcoming haze and underwater imaging; Spaceborne multiview recovery; computational imaging on the electric grid; illumination multiplexing; 3D shape estimation based on defocus and diffracted-rotated PSFs; separation and reconstruction of semireflections and transparent layers; polarization and multispectral imaging; radiometric self-calibration; overcoming and exploiting lens-flare and random illumination caustics; recovery limits under pointwise degradations; audio-visual analysis.

Some of the studies involve statistical frameworks to achieve blind estimation. Here is a Wordl based on the research page:
