- There is now a downloadable software package called mkhdr available for assembling high dynamic range radiance maps from series of photographs. These images are in the RADIANCE Synthetic Imaging System image format (Described in Greg Ward's "Real Pixels" article in Graphics Gems II .) They can be viewed on an X11 display using the ximage ...

- ABSTRACT. We present a method of recovering high dynamic range radiance maps from photographs taken with conventional imaging equipment. In our method, multiple photographs of the scene are taken with different amounts of exposure. Our algorithm uses these differently exposed photographs to recover the response function of the imaging process, up …

- The goal of HDR image processing is to use a series of photographs of a scene to produce an image that is as close as possible to what the human eye would see. To turn a photograph into an HDR image, we first extract the radiance information from the photographs and then tone-map it into a single low dynamic range image.

- Abstract: An influential technique introduced by Debevec and Malik has become the de facto standard for recovering high dynamic range radiance maps from photographs and has been widely used in research and commercial systems for over a decade. However, we have discovered an important defect in the original algorithm that will make this technique often fail …

- f ( X) = Z X = f − 1 ( Z), (1) (1) f ( X) = Z X = f − 1 ( Z), Then the reconstruction of the irradiance map from the pixel values can be obtained by applying inverse f f, where f f is assumed to be a smooth and continuous function. Eq.1 can be expressed with pixel ( i i) and image ( j j) indices as follow.
