Diminished fact is a brand new attention-grabbing expertise that gets rid of real-world content material from reside video streams. This sensational reside video manipulation truly gets rid of actual items and generates a coherent video movement in real-time. audience can't realize changed content material. current ways are limited to relocating items and static or nearly static cameras and don't permit real-time manipulation of video content material. Jan Herling offers a brand new and leading edge method for real-time item elimination with arbitrary digital camera movements.

85] Fang et al. [34] Kwok et al. [65] Bugeau et al. [21] Xu et al. 1: Summary of the introduced image inpainting approaches. A simplified overview is given to compare the most significant differences between the individual approaches. 4 Image Manipulation In the following subsection, recent image synthesis approaches are introduced to manipulate image content not only by image inpainting but also by image reshuffling or image resizing. 1 Patch-based Similarity by Simakov et al. 2009 Simakov et al. proposed a patch-based approach to manipulate images by iteratively updating the image content.

The sole application of image warping cannot compensate changing lighting conditions and thus may produce unrealistic inpainting fragments. Warping does not allow integration of more detailed visual information in the following video frames with zooming camera motion. Still other approaches such as the approaches of Wexler et al. [103], Shiratori et al. [90] or Liu et al. [71] do not warp the image content of the first video frame, but inpaint a 3D image block instead. Although our previous approach [40] allowed a real-time execution for video inpainting, high performance was a trade-off between speed and image quality.

During sequences with high rotational camera motions or shaking movements, frame coherence sometimes failed. Significant optimization and modifications were applied to our previous approach to end up with a real-time approach. , of Barnes et al. In Chapter 4, an image inpainting approach will be described that is faster than our previous approach while providing significantly higher image quality. A detailed comparison of benchmark images between the previous and the current approach is given showing the differences between both approaches.
