International Workshop on Chaos-fractals Theories and Applications
作者: Jiang, Aiping Han, Yulan Heilongjiang Univ Coll EE Harbin Peoples R China
A new fractal watermarking algorithm is proposed, in which the watermark embedded can be extracted well. To achieve high-quality extracted watermark under some image attacks, the algorithm selects a suitable image arb... 详细信息

Conference on Visual Communications and image Processing 2005
作者: Lai, CM Lam, KM Siu, WC Hong Kong Polytech Univ Ctr Multimedia Signal Proc Dept Elect & Informat Engn Hong Kong Hong Kong Peoples R China
In this paper, a new fractal-based image denoising method is proposed which can reserve the edges and remove the blocky artifacts in a denoised image. Our proposed method employs the decoupling property of the fractal... 详细信息

Conference on Electronic Imaging and Multimedia Technology III
作者: Zhang, ZB Jianghan Petr Univ Dept Elect & Informat Engn Jinzhou 434023 Hubei Peoples R China
Edge detection is important in many fields such as pattern recognition and computer vision. Many edge detection methods are sensitive to noises because gradients are used to enhance edges. To solve this problem, a new... 详细信息

Conference on Visual Communications and image Processing 2001
作者: Erickson, AJ Shaaban, ME Hsu, KW Czernikowski, RS IBM Microelect Essex Jct VT USA
fractal image compression has several useful properties, including resolution independence, high compression ratios, rapid decoding, and subjectively good image quality. Despite this, its adoption has been limited, la... 详细信息

WAVELETS AND fractal image COMPRESSION BASED ON THEIR SELF-SIMILARITY OF THE SPACE-FREQUENCY PLANE OF imageS
收藏 引用
International Journal of Wavelets, Multiresolution and Information Processing 2003年 第4期1卷 393-405页
作者: YOSHITO UENO Graduate School of Engineering SOKA University 1-236 Tangi-cho Hachioji-shi Tokyo 192-8577 Japan
This paper presents a fusion scheme for wavelets and fractal image compression based on the self-similarity of the space-frequency plane of sub-bands after wavelet transformation of images. Various kinds of wavelet tr... 详细信息
