In this paper, we formulate the problem of natural image matting as one of solving Poisson equations with the matte gradient field. Our approach, which we call Poisson matting, has the following advantages. First, the matte is directly reconstructed from a continuous matte gradient field by solving Poisson equations using boundary information from a user-supplied trimap. Second, by interactivel...

Poisson Matting Based on Exemplar-Based Inpainting

Matting is the process of pulling an alpha and foreground from an image or video sequence. It is used for compositing the foreground objects into different scene. It has an important role in film and video production; it enables directors to embed actors in any world such as world that exists only in our imagination. There are several techniques that can be used to pull the matte such as Poisso...

Video-Based Interactive Storytelling

This thesis proposes a new approach to video-based interactive narratives that uses real-time video compositing techniques to dynamically create video sequences representing the story events generated by planning algorithms. The proposed approach consists of filming the actors representing the characters of the story in front of a green screen, which allows the system to remove the green backgr...

A Literature Review of Image Segmentation Techniques and Matting for the Purpose of Implementing “Grab-Cut”

This literature review attempts to provide a brief overview of some of the most common segmentation techniques, and a comparison between them. It discusses the “Grab-Cut” technique, and reviews some some of the common matting techniques. The graph cut approaches to segmentation can be extended to 3-D data and can be used for segmenting 3-D volumes. Other segmentation techniques use either conto...

Bayesian Video Matting Using Motion Based Segmentation

Video matting attempts to extract foreground images from an image sequence, as well as the alpha-mattes that describe their transparency. This papers presents an automated video matting framework using motion-based segmentation and bayesian matting. We build upon existing techniques for layer segmentation based on optical flow to generate a coarse trimap, by identifying image pixels as belongin...
