>     Conference Report, SIGGRAPH Asia (Pradeep)

Thanks, Tobias.  FYI everyone, I plan to give the presentation of our
paper on HDR reconstruction for dynamic scenes (see abstract below),
and then cover briefly some of the other papers that might be of
interest to folks in the 4-Eyes lab.

Thanks!

TITLE
Robust Patch-Based HDR Reconstruction of Dynamic Scenes


ABSTRACT
High dynamic range (HDR) imaging from a set of sequential exposures is 
an
easy way to capture high-quality images of static scenes, but suffers 
from
artifacts for scenes with significant motion. In this paper, we propose 
a
new approach to HDR reconstruction that draws information from all the
exposures but is more robust to camera/scene motion than previous 
techniques.
Our algorithm is based on a novel patch-based energy-minimization 
formulation
that integrates alignment and reconstruction in a joint optimization 
through
an equation we call the HDR image synthesis equation. This allows us to 
produce
an HDR result that is aligned to one of the exposures yet contains 
information
from all of them. We present results that show considerable improvement 
over
previous approaches.
