Report: State-of-the-Art DE-ghosting Algorithms for High Dynamic Range Imaging

Abstract

High Dynamic Range Imaging (HDRI) may be generated by combining multiple low dynamic range (LDR) images of the same scene with different exposures. However, this technique of generating HDR images is limited to static scenes. During capturing of LDR images, any changes in the scene between different captures caused by either camera shake or object motion results in ghost artifacts in the produced HDR image. These ghost artifacts make the same object appear more than once in the generated HDR image. As a result, deghosting algorithms have been developed over the past years in an attempt to remove any ghosting present in HDR images.This article is a report of  „State-of-the-art deghosting algorithms for generating HDR images“(Karađuzović-Hadžiabdić K., and Hasić Telalović J., 2013).
