A Hybrid Patching Scheme for High Dynamic Range Imaging
It is very challenging to synthesize a high dynamic range (HDR) image by using a set of differently exposed low dynamic range (LDR) images that are captured with moving objects. This is due to the fact that the moving objects cause ghosting artifacts in the synthesized HDR image. To remove these artifacts, an anti-ghost algorithm is necessary for detection and patching of motion regions, and the patching plays an important role in the synthesis of an HDR image with moving objects. In this paper, a hybrid scheme for patching of motion regions is introduced. The proposed patching scheme is a scheme which is composed of a pixel level intensity mapping function (IMF) and a block level template matching. Experimental results show that the proposed patching scheme outperforms existing IMF based patching schemes.
