Multiview-Consistent Color Sampling for Alpha Matting
نویسندگان
چکیده
We propose a method for incorporating multiview information into color sampling methodologies for alpha matting. We extend the typical trimap input for matting algorithms to 3D space, enabling the association of stripes of pixels in semi-transparent regions like hair between different views without knowing or inferring their spatial structure. We also formulate a new cost function penalizing deviations of foreground color estimates between associated pixel stripes and its possible integration into a state-of-the-art color sampling approach.

Multiview foreground extraction and composition to multiview background using trimap sharing for natural 3D scene generation
Digital matting for extracting foreground objects from an image is an important process to generate special effects in the movie industry and the broadcasting center. Recently, a digital matting algorithm has been developed to create an alpha matte using a well-focused image generated from multiview images. However, this method could generate only a single-view alpha matte, even though it used ...
متن کاملImage Forgery Using An Enhanced Bayesian Matting Algorithm
The development of forgery techniques for multimedia has recently become an important research topic. This paper proposes a new method to construct a tampered image based on the matting approach. Most previous matting techniques focus on the alpha estimation of the source image, since an accurate alpha matte can help with compositing the selected object into a new scene. However, the lighting c...
متن کاملLocal and Nonlocal Color Line Models for Image Matting
In this paper, we propose a new matting algorithm using local and nonlocal neighbors. We assume that K nearest neighbors satisfy the color line model that RGB distribution of the neighbors is roughly linear and combine this assumption with the local color line model that RGB distribution of local neighbors is roughly linear. Our assumptions are appropriate for various regions such as those that...
متن کاملShared Sampling for Real-Time Alpha Matting
Image matting aims at extracting foreground elements from an image by means of color and opacity (alpha) estimation. While a lot of progress has been made in recent years on improving the accuracy of matting techniques, one common problem persisted: the low speed of matte computation. We present the first real-time matting technique for natural images and videos. Our technique is based on the o...
متن کاملConsistent Matting for Light Field Images
We present a new image matting algorithm to extract consistent alpha mattes across sub-images of a light field image. Instead of matting each sub-image individually, our approach utilizes the epipolar plane image (EPI) to construct comprehensive foreground and background sample sets across the sub-images without missing a true sample. The sample sets represent all color variation of foreground ...
