Simplified weighting function for high dynamic range video frame formation

High Dynamic Range Video

High Dynamic Range Video Chains

Over the last decade, much research experience has been gained in the realm of high dynamic range imaging (HDRI). On account of the significantly improved visual experience that HDRI offers, industry has recently taken a strong interest in this set of technologies. This is evident in the active consideration of HDR by standardization bodies, for instance DVD and EBU in the context of UHDTV, and...

Stereoscopic High Dynamic Range Video

Stereoscopic video content is usually being created by using two or more cameras which are recording the same scene. Traditionally, those cameras have the exact same intrinsic camera parameters. In this project, the exposure times of the cameras differ, allowing to record different parts of the dynamic range of the scene. Image processing techniques are then used to enhance the dynamic range of...

High Dynamic Range Video with Ghost Removal

We propose a new method for ghost-free high dynamic range (HDR) video taken with a camera that captures alternating short and long exposures. These exposures may be combined using traditional HDR techniques, however motion in a dynamic scene will lead to ghosting artifacts. Due to occlusions and fast moving objects, a gradient-based optical flow motion compensation method will fail to eliminate...

High Dynamic Range Video Camera with Webcams

There are a variety of techniques for combining the three different images into a single image, but the main limitation is the dynamic range of the media that the photo will finally be displayed on. Paper and digital monitors, like digital sensors, are “low dynamic range” devices, and thus cannot demonstrate the greater dynamic range that has been captured. Tonemapping is one process by which h...
