Additional Results for HDR Alignment

This page provides further results concerning our proposed optic flow-based alignment strategy for HDR imaging. To demonstrate the possibilities of our approach, we applied it to several real world exposure series that were taken handheld using a standard DSLR camera (Nikon D90). To illustrate the amount of displacements in the series, we additionally show HDR reconstructions without alignment.

Note that all results shown here were obtained using a fixed set of parameters which can be found in the paper.

We offer zip archives for download, which contain all images in JPEG format so that all important information (such as exposure times) are available from the EXIF headers.
To visualise the HDR images, we applied the tone mapping operator of Fattal et al. as implemented in the pfstools package. In addition, we offer to download the HDR images in the RGBE format proposed in G. Ward: Real Pixels. Graphics Gems II, Academic Press, 1992. A C implementation of a read/write library for RGBE data can be found here.
