A tone mapping algorithm for displaying high contrast scenes was designed on the basis of the results of experimental tests using human subjects. Systematic perceptual evaluation of several existing tone mapping techniques revealed that the most “natural” appearance was determined by the presence in the output image of detailed scenery features often made visible by limiting contrast and by pro...

Video recording and photography are frequently used to document Cultural Heritage (CH) objects and sites. High Dynamic Range (HDR) imaging is increasingly being used as it allows a wider range of light to be considered that most current technologies are unable to natively acquire and reproduce. HDR video content however has only recently become possible at desirable, high definition resolution ...

Due to technical limitations, common display devices can only reproduce images having a low range of intensity values (dynamic range). As a consequence, the dynamic range of images encoding real world scenes, which is large, has to be compressed in order for them to be reproduced on a common display, and this technique is called tone mapping. Because there is no ground truth to compare with, ev...

RÉSUMÉ. La HDR (High Dynamic Range) permet de représenter des images d'une manière analogue à la représentation de notre système de vision et de manière plus complexe que dont nous disposons à l'heure actuelle sur notre ordinateur. Cet article propose d'analyser le comportement des extracteurs de points d'intérêt spatiaux et spatio-temporels lors de leur utilisation sur des vidéos HDR en les co...

We present a technique for embedding high dynamic range (HDR) images with interactive exposure control in a web browser. Multiple exposures are encoded as a combination of several basis images, which are stacked together and displayed with different opacity values. The combination of such basis images yields the resulting exposure image. An intuitive interface based on JavaScript callback funct...

Images taken by typical digital cameras with fixed exposure often suffer from a lack of details in the underexposed and overexposed regions. Fusing multi-exposed images is particularly useful for improving this situation. This paper proposes a weighted-sum-based multi-exposure image fusion method that is fast enough to be implemented in digital cameras. The proposed method attempts to improve t...
