Fence Removal from Multi-focus Images

When an image of a scene is captured by a camera through a fence, a blurred fence image interrupts objects in the scene. In this paper, we propose a method for a fence removal from the image using multiple focusing. Most of previous methods interpolate the interrupted regions by using information of surrounding textures. However, these methods fail when information of surrounding textures is not rich. On the other hand, there are methods that acquire multiple images for image restoration and composite them to generate a new clear image. The latter approach is adopted because it is robust and accurate. Multi-focus images are acquired and ``defocusing'' information is utilized to generate a clear image. Experimental results show the effectiveness of the proposed method.
