Blind Deghosting for Automatic Multi-exposure Compositing
Vision & Image Processing Lab, Department of Electrical Engineering, IIT Bombay, India
Abstract
High dynamic range (HDR) image, which faithfully represents the
real world scene, needs to be tone mapped to a low dynamic range
(LDR) image for display/printing purposes. In this work, we propose
a novel method to generate an LDR image of a dynamic scene
directly from multi-exposure images, captured using methods like
Auto-Exposure Bracketting (AEB). Though there are methods such
as [Mertens et al. 2009] for producing such an LDR image, they
produce artifacts called ghosts in case of moving objects in the
scene. We propose a novel approach to determine the moving objects
and eliminate them while compositing. We do not assume any
knowledge of camera response function and the exposure settings,
a must for existing works like [Gallo et al. 2009]. We show that the
resultant LDR images are artifact-free and are faithful representations
of the HDR images.
