Abstract: During the past few decades, highly sensitive cameras able to take high dynamic range photographs have been developed. Unfortunately, screens have not kept pace with this rising technology and what is currently faced is the inability to display HDR images on conventional displays. As a workaround, many techniques that attempt to compress the original image so it can be displayed on a conventional screen have been proposed, but their results differ greatly depending on the input image. What this paper aims to achieve is an improvement in the overall results of such techniques by implementing a voting system between existing tone-mapping algorithms based on alternating the algorithms or modifying their internal input parameters. In addition, the paper also presents a new and improved tone-mapping algorithm resembling the existing ones but faster and which yields satisfying results.
