چکیده

We present a new approach to display High Dynamic Range (HDR) video using gradient based high dynamic range compression. To obtain HDR video, we utilize the split aperture camera. We apply a spatio-temporal gradient based video integration algorithm for fast and accurate integration of the three input HDR videos into a low dynamic range video, which is suitable for display. The spatiotemporal video integration generates videos with temporal coherency and without artifacts. In order to improve the computational speed, we propose using a diagonal multigrid algorithm to solve the Poisson equation. We show experimental results on a variety of dynamic scenes.

Multiple-Aperture Photography for High Dynamic Range and Post-Capture Refocusing

In this article we present multiple-aperture photography, a new method for analyzing sets of images captured with different aperture settings, with all other camera parameters fixed. Using an image restoration framework, we show that we can simultaneously account for defocus, high dynamic range exposure (HDR), and noise, all of which are confounded according to aperture. Our formulation is base...

Multiple Exposure Image Fusion

in many cases scene’s dynamic range is greater than digital camera dynamic range. In such cases the user needs to capture multiple exposures of the same scene, then combines them together. Exposure can be varied either by changing the shutter speed or by changing the aperture. In this paper we preferred to change the shutter speed over aperture. The main reason for that is changing aperture lea...

Dynamic Depth of Field on Live Video Streams: A Stereo Solution

The ability to produce dynamic Depth of Field effects in live video streams was until recently a quality unique to movie cameras. In this paper, we present a computational camera solution coupled with real-time GPU processing to produce runtime dynamic Depth of Field effects. We first construct a hybrid-resolution stereo camera with a high-res/low-res camera pair. We recover a low-res disparity...
