Glare-limited Appearances in HDR Images
Color and Imaging Conference, 2007Appearance in High Dynamic Range (HDR) images is controlled by intraocular glare and simultaneous contrast. This paper describes unique test targets that simulate real images. They change the HDR range by 500 times without significantly changing the veiling glare on the retina. As well, these targets have nearly constant simultaneous contrast.

Camera Identification from HDR Images
Proceedings of the ACM Workshop on Information Hiding and Multimedia Security, 2019Performance of camera identification methods based on PRNU is very sensitive to geometric operations applied to images during acquisition and processing. Handling images that have been geometrically transformed, such as rotated, downsampled, and/or cropped requires overcoming pixel desynchronization problem.

Shape Recovery Using HDR Images
Computer Graphics, Imaging and Visualisation (CGIV 2007), 2007In this paper, an effective method for shape recovery using HDRI (high dynamic range images) is proposed. Firstly, an accurate reflectance map for a reference sphere relating its radiance values and corresponding normals is established, then the set of candidate normals of each target point comprising the same material are found by comparing its ...

An improved HDR image synthesis algorithm
2009 16th IEEE International Conference on Image Processing (ICIP), 2009In high dynamic range (HDR) imaging, multiple photographs with different exposure times are combined into a radiance map, which reflects the radiance in real-life scenes. This involves recovering the response function of the imaging process. The technique proposed by Debevec and Malik is a well-known HDR image synthesis algorithm, but the computational

Objective HDR image quality assessment
Multimedia Tools and Applications, 2018Although there is a lot of literature about generating HDR images, very limited research has been conducted on the issue of HDR image quality based on people’s feeling and preferences. The goal of this paper is to identify an objective quality measurement of an HDR image.
