LDR Image from HDR by Using Fast and Saliency Based Tone-Mapping Algorithm: A Review (original) (raw)

2015

Abstract

This paper presents a comparatively analysis of the fast and saliency feature based tone mapping technique. After analysis of these techniques we had concluded that fast tonemapping algorithm is most computationally efficient and easy but there may be some halo artifacts. While in Visual-Salience-based Tone mapping method for High dynamic range images the halo artifacts significantly reduced. Thus salience based tone mapping gives best visual image quality as compared to fast tone mapping method. The visual quality of tone-mapped image, especially attention-salient regions, is improved by the saliency-aware weighting. Experimental results show that the saliency-aware technique produces good results on a variety of high dynamic range images.
