A System for Displaying High Dynamic Range Spectral Image Using Local Tone Mapping

Abstract

In this paper, we propose a system for displaying high dynamic range spectral (HDRS) images using local tone mapping. HDRS images store light intensity according to the wavelength of light using more than 8 bits for each voxel. Since HDRS images are much larger than conventional RGB images, they require higher computational cost for displaying. The proposed system operates in two stages; 1) compressing and recording an HDRS image, and 2) uncompressing and displaying it. In the displaying process, we use a local tone mapping based on bilateral filtering. The system can display an HDRS image interactively with various parameter settings using a graphical user interface.
