Abstract:

It is the age of fast and good quality Digital images, those are subject to blurring due to many hardware limitations, such as atmospheric disturbance, apparatus noise and poor focus quality. Visual saliency aims to predict the attentional steady intent look of observers viewing a scene, and therefore tone mapping of high dynamic range (HDR) images concept is highly useful for it. The work has focused on incorporation of saliency-aware weighting and edge-aware weighting into local tone-mapping algorithms for HDR images. The visual quality of the tone-mapped resultant image, especially the attention-salient areas, will be improved by the saliency-aware weighting. Experiments show that the proposed global scale tone mapping technique produces good results on a variety of high dynamic range images.
