Seeing through the fence: Image de-fencing using a video sequence
Tourists and amateur photographers are often hindered in capturing their cherished images/videos by a fence/occlusion that limits accessibility to the scene of interest. The situation has been exacerbated by growing concerns of security at public places and a need exists to provide a tool that can be used for post-processing such “fenced videos” to produce a “de-fenced” image. There are several challenges in this problem and in this work, we identify them as 1. Robust detection of the fence/occlusions. 2. Estimating pixel motion of background scene. 3. Filling in the fence/occlusions by utilizing information in multiple frames of the input video. We use a video captured by a camera panning the scene containing a fence and obtain a “de-fenced” image. Our method can effectively remove fences from images as demonstrated for several synthetic and real-world cases.
