After analysis of these techniques we had concluded that fast tone-mapping algorithm is most computationally efficient and easy but there may be some halo artifacts are present. While in Visual-Salience-based Tone mapping method for High dynamic range Images 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 the tone-mapped image, especially attention-salient regions, is improved by the saliency-aware weighting. 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. While Faster Tone mapping of High Dynamic Range Images method present a fast, effective and flexible tone mapping method that preserves visibility and contrast impression of high dynamic range scenes in low dynamic range reproduction devices. Experiments show that the saliency-aware technique produces good results on a variety of high dynamic range images.
