Natural Matting of Complex Scenes
Image matting has been used for a long time in the movie industry to combine several picture elements into a final image. Typically an actor or similar is considered the foreground and extracted from the filming environment. The resulting matte is then used to place the foreground onto a different background by applying alpha blending. One of the most common techniques for the matting procedure...
متن کاملVideo Inpainting of Complex Scenes
We propose an automatic video inpainting algorithm which relies on the optimisation of a global, patch-based functional. Our algorithm is able to deal with a variety of challenging situations which naturally arise in video inpainting, such as the correct reconstruction of dynamic textures, multiple moving objects and moving background. Furthermore, we achieve this in an order of magnitude less ...
متن کاملSpectral Video Matting
We present a new, simple-to-use and rapid approach to video matting, the process of pulling a highquality alpha matte from a video sequence. Our approach builds upon techniques in natural image matting, namely spectral matting, and optical flow computation. No additional hardware, despite a single camera, is needed, and only very few and intuitive user interactions are required for foreground e...
متن کاملVideo Matting from Depth Maps
Image matting is the process of computing an alpha value for each pixel that corresponds to the amount of the pixel that is foreground and the amount that is background. This is often used to isolate the foreground and replace the background with a different image. Typically this is done using a special studio and a blue (or green) screen for easier segmentation. However, this method is not as ...
متن کاملNatural Video Matting with Depth
Video matting is the process of taking a sequence of frames, isolating the foreground, and replacing the background with something different in each frame. This is an under-constrained problem when the background is unknown. Matting techniques exist to approximate these values using manual input cues. We look at existing singleframe matting techniques and present a method that improves upon the...
