There are a number of modern myths about High Dynamic Range (HDR) imaging. There have been claims that multiple-exposure techniques can accurately record scene luminances over a dynamic range of more than a million to one. There are assertions that human appearance tracks the same range. The most common myth is that HDR imaging accurately records and reproduces actual scene radiances. Regardles...

We presented a survey on High-dynamic-range imaging (HDRI or HDR) is a set of methods used in the imagingand photography to reproduce a superior dynamic range of luminosity than regular digital imaging or photographic methods can do. HDR images can denote a superior range of the luminance levels than can be attained using the extra 'classical' techniques. Images such as those holding many actua...

In this report we propose a HDR synthesis framework based on MAP estimation. We start with introducing a physical model for the HDR imaging process, and then make several basic assumptions. Based on these we reach a model where our previous formulation on HDR deghosting could be considered an instantiation, by picking particular densities and choosing appropriate parameters. Finally, we extend ...

High dynamic range image (HDR) is widely used since it is capable of capturing more fine information. However, problems remain in its display. A good rendering of HDR color images requires careful treatment of both the brightness and chromaticity information. In this work, we first prove that the global logarithmic mapping of the R, G, B channels may result in desaturation. We then propose an i...
