Abstract

While tone mapping operation of high dynamic range (HDR) images for realistic display is commonly researched, scientific visualization for analyzing scene luminance within HDR image has much less attention from researches. This paper has presented and implemented an approach for the reproduction and visualization of the colour information in HDR images. We attempt several simple color visualizing functions, and estimate their effectiveness through the evaluation factors with common HDR images. The experimental result shows that sigmoidal mapping function is better performance in the visualization, compared to other approaches.
