Abstract

The problem of tone mapping for HDR (high dynamic range) to LDR (low dynamic range) conversion is introduced by a unified framework considering all the usual processing steps. Then the specific problem of single-shot HDR is outlined where special emphasis is taken on the effect of the greater noise floor of those images when compared to the usual exposure bracketing approach to HDR. We herein tailor the popular tone mapping operators proposed by Reinhard for single-shot HDR. A region-based approach for preprocessing any HDR image in order to increase SNR and perceptual sharpness is introduced as an extension to our initial tone mapping framework. The results are compared with respect to specially developed baseline tone mappers and an extensive subjective evaluation is performed.
