Cover Story: Spectral super-resolution (SSR), which reconstructs hyperspectral (HS) images from RGB images, has been actively studied. Conventional SSRs target low dynamic range images. On the other hand, in some applications of HS images such as physically based rendering, high dynamic range (HDR) images are required for realistic image synthesis. We propose a novel SSR to support HDR-HS image reconstruction. As a practical example, we use reconstructed HDR-HS images to render a silicon object coated with a thin film in cooperation with image-based lighting. The top row shows the results using conventional methods (a, b) and our method with the HDR-HS environment map (c). The bottom row shows the difference between each rendered image and the reference image. View this paper
