| Abstract(in English) | Vector representation has an advantage of keeping high image quality for arbitrary scaling. In recent years, a demand for scalable video coding has been increasing for the diversity of digital contents and display terminals. Conventional scalable video coding schemes are based on raster representation, and thus, line drawings deteriorate in quality when they are expanded and/or shrunk. In this paper, we propose an edge reconstruction method using vector representation for the purpose of keeping a consistent temporal scalability on transmission and display. We consider an anti-aliasing process in edge areas and approximate luminance values around the edge. We can display images at any scale by this method. Validity of the proposed methods is confirmed by quality assessment when the image is expanded and shrunk. |
