Diminished truth is a brand new attention-grabbing expertise that gets rid of real-world content material from reside video streams. This sensational stay video manipulation really gets rid of genuine gadgets and generates a coherent video move in real-time. audience can't become aware of transformed content material. latest techniques are limited to relocating items and static or virtually static cameras and don't permit real-time manipulation of video content material. Jan Herling offers a brand new and leading edge procedure for real-time item removing with arbitrary digital camera movements.

Example text

In the first video frame, an undesired object is roughly selected by the user. Active contour detection begins using this rough user-defined selection. The contour is iteratively refined. The resulting contour precisely encloses the undesired object. 17: Scheme of the active contour tracking approach. a) Undesired object with rough user-defined contour, b) several iterative refinement steps finding the final precise contour, c) resulting inpainting mask. to find the precise contour for the next frame. 17, the simple active contour tracking approach is depicted.

2005 The video inpainting approach presented by Patwardhan et al. [77, 78] is only able to process video streams captured with an absolute static camera. In principal, they apply a 3D version of the static patch-based image inpainting approach of Criminisi et al. [25]. 2 Video Inpainting 35 moving objects in front of a static background or the inpainting of a static background preserving a moving object. For the case that a moving object has to be removed, the approach has two steps. In the first trivial step, missing information is simply copied from different video frames in which the moving object is at a different position and the original background information is visible.

2004 Jia et al. [53, 54] proposed one of the first video inpainting approaches to repair damaged video sequences. They proposed to manually separate the video sequence into foreground and background content. Visual elements from the background content have to be static, foreground elements are moving objects. The approach allows removal of static background objects while repairing the video sequence for moving foreground elements. , to remove a static tree, while in the video sequence a person crosses in front of the tree.
