Obtaining a foreground silhouette across multiple views is one of the fundamental steps in 3D reconstruction. In this paper we present a novel video segmentation approach, to obtain a foreground silhouette, for scenes captured by a wide-baseline camera rig given a sparse manual interaction in a single view. The algorithm is based on trimap propagation, a framework used in video matting. Bayesia...

Most matting researches resort to advanced semantics achieve high-quality alpha mattes, and direct low-level features combination is usually explored complement details. However, we argue that appearance-agnostic integration can only provide biased foreground details mattes require different-level feature aggregation for better pixel-wise opacity perception. In this paper, propose an end-to-end...

Image matting is a key technique for image and video editing composition. Conventionally, deep learning approaches take the whole input an associated trimap to infer alpha matte using convolutional neural networks. Such set state-of-the-arts in matting; however, they may fail real-world applications due hardware limitations, since images are mostly of very high resolution. In this paper, we pro...

We consider a multi-zone segmentation of a single image when user-supplied seeds are provided in each region. We view this task as a statistical transductive inference, in which some pixels are already associated with given zones and the remaining ones need to be classified. Our method relies on the Laplacian graph regularizer, a powerful manifold-learning tool that is based on the estimation o...

This work addresses the problem of video matting, that is extracting the opacity-layer of a foreground object from a video sequence. We introduce the notion of alpha-flow which corresponds to the flow in the opacity layer. The idea is derived from the process of rotoscoping, where a user-supplied object mask is smoothly interpolated between keyframes while preserving its correspondence with the...

In this paper, an image cloning method called arbitrary cloning is presented, in which image matting and Poisson image editing techniques are applied. The object boundary is extracted through image matting technique while Poisson equation is solved to achieve natural result for seamless cloning. Compared with existing techniques, the proposed approach gains a great deal of advantages: On the on...

Mining interesting objects with trimap guidance and fusing multi-level features are two important issues for trimap-based matting. For feature mining, existing methods simply feed trimaps to an encoder network mine evenly in different regions a decoding module, which lacks efficient effective way pointed out by trimaps. emerging content-based fusion, most matting only focus on local lack the of...
