This paper presents a novel pixel-based multi-resolution texture synthesis algorithm. First, pyramids are constructed for the sample and output separately, and a novel method is designed to synthesize the lowest resolution texture so that a real-time pattern matching algorithm can be used to expedite the neighborhood matching. Then, to sweep out the artifacts and improve the synthesis quality, iterative...
This paper presents an interactive algorithm for natural image matting. Given a few user-marked foreground and background strokes, the unmarked region of the input image is modeled as a Markov random field (MRF) and its energy function is formulated as the sum of the local energy of the unmarked pixels. The opacity matte is extracted by constructing a cellular automaton on the image, of which each...
