A fast progressive image transmission scheme using block truncation coding by pattern fitting
收藏 引用
JOURNAL OF VISUAL COMMUNICATION AND IMAGE REPRESENTATION 2012年 第2期23卷 313-322页
作者: Dhara, Bibhas Chandra Chanda, Bhabatosh Jadavpur Univ Dept Informat Technol Kolkata India Indian Stat Inst Kolkata India
In this paper, we have proposed a novel progressive image transmission scheme. In the present method, the concept of the BTC-PF is used for faster decoding. Here, images are decomposed into a number of blocks based on... 详细信息

Joint Compression/Watermarking Scheme Using Majority-Parity Guidance and Halftoning-Based block truncation coding
收藏 引用
IEEE TRANSACTIONS ON IMAGE PROCESSING 2010年 第8期19卷 2056-2069页
作者: Guo, Jing-Ming Liu, Yun-Fu Natl Taiwan Univ Sci & Technol Dept Elect Engn Taipei Taiwan
In this paper, a watermarking scheme, called majority-parity-guided error-diffused block truncation coding (MPG-EDBTC), is proposed to achieve high image quality and embedding capacity. EDBTC exploits the error diffus... 详细信息
