Abstract:
It is very challenging to synthesize a ghosting-free high dynamic range (HDR) image using differently exposed low dynamic range (LDR) images with moving objects. To achieve this, an anti-ghosting scheme is required to detect and patch occluded motion regions. In this poster, a new optimization problem is formulated on patching motion regions along a differently exposed image sequence, which optimizes consistencies in both spatial and temporal domain. To solve this optimization problem, a hybrid patching scheme including pixel-level intensity mapping function and block-based template matching is proposed.
