| Abstract(in English) | In natural image matting where an object is extracted from a photograph with natural background and is composited with another image, a user is required to input strokes specifying both of foreground and background regions for supporting the extraction of the target object. In order to reduce user's inputs, we apply, in this paper, a semi-supervised algorithm for extracting a fuzzy cluster from similarity data to this task, and present a method for extracting an object from a natural image by propagating memberships from seeded pixels to the remaining area according to the similarity between pixel colors transformed with the Fisher's linear discriminant analysis. In our method, rough and coarse strokes are sufficient for users to draw them only either in foreground regions or in background areas. The color of the extracted object is estimated at each pixel based on the membership obtained with this algorithm and the extracted object is composited with another image as a new background. |
