A Novel Quadtree-Structured Scheme for Transmitting Chinese Calligraphy Progressively

Abstract

Progressive image transmission (PIT) techniques are useful in Web applications. A user can get a rough preview of an image and decide if the entire detail of a picture needs to be transmitted, especially when the network bandwidth is restricted. In this paper, we propose a new progressive image transmission scheme for Chinese calligraphy. Because the colors used in Chinese calligraphy are very simple, we can apply the quadtree-structure to transmit the calligraphy progressively. The preliminary results show that transmitted bits can be saved in the first few rounds. The PSNR values in the first few rounds are much better than other PIT techniques.
