It is known that high dynamic range image can be recovered by a set of conventional images shooting at the same scene but with different exposure levels. However, ghost artifacts are commonly seen due to the movement of the object between different captures. In this paper, we propose a real-time algorithm to detect and remove the ghost artifact based on four simple procedures: 1) Inter-pixel Relationship...
The contrast in real world scenes is often beyond what consumer cameras can capture. For these situations, High Dynamic Range (HDR) images can be generated by taking multiple exposures of the same scene. When fusing information from different images, however, the slightest change in the scene can generate artifacts which dramatically limit the potential of this solution. We present a technique capable...
The high dynamic range image (HDRI) acquisition method based on Markov random field model is proposed. By combining multiple exposure images shot with different shutter speed, we estimate the irradiance value for each pixel. Our method estimates displacements, occlusion and saturated regions, and by using them construct the motion blur free HDRI with higher quality than other existing methods.
