Abstract/Summary: Our recent works have developed simple and effective tone mapping operators for the visualization of high dynamic range images (Duan and Qiu 2004; Duan et. al., 2005; Qiu and Duan 2005; Qiu et. al., 2006a and 2006b). These techniques enable the visualization of high dynamic range colour photographs (32 bits per channel (Reinhard et. al., 2005)) in low dynamic range reproduction media such as monitors and printing papers. These operators work to equally distribute the image data under the constraint that the output should also be faithful to the input data’s original distribution, thus having the advantage of enhancing contrast, preserving the original image’s visual appearance and at the same time being free of artefacts. Scientific image visualization often requires improved contrast, vivid colour appearance and artefact free. In this paper, we will discuss how tone mapping operators developed for high dynamic range photographs can be applied to the visualization of scientific images for improved visualization.
