A Geometric Method for Imaging through Turbulence
Abstract
The phenomenon that is commonly referred to as "turbulence" in imaging
is caused by the time and space-varying refraction index of the air
which is due, among other factors, to temperature, air pressure,
humidity, and wind conditions between the acquired scene and the
image-capturing device. The resulting image sequence is also affected
by the different and changing lighting conditions within the scene, by
the actual distance between the observed objects and the camera, and
by other artifacts introduced by the device itself. In this talk we
will describe the problem of reconstructing the underlying image in
mathematical terms, and introduce a new method based on concepts from
geometry and PDEs.
L’exposé sera en français.
