  • A Chinese Remainder Theorem Oriented Information Hiding Scheme 

    Chang, Chin-Chen; Lu, Tzu-Chuen (The Eurographics Association, 2004)
    Steganography is an information hiding technique that conveys secret information in a host signal using a secret method. Only the receivers and senders know the secret information. Many researchers have proposed their own ...
  • Content Based Image Public Watermarking 

    Hengfu, Yang; Zihua, Yang; Mingfang, Jiang (The Eurographics Association, 2004)
    In this paper, a content based image public watermarking technique which operates in DCT domain is proposed. First, the 8×8 DCT sub-blocks of the host image are rearranged into a Hilbert sequence in Hilbert scanning order, ...
  • A Segmentation Algorithmfor Jacquard Images Based on Mumford-ShahModel 

    Feng, Z. L.; Yin, J. W.; Chen, G.; Liu, Yang; Dong, J. X. (The Eurographics Association, 2004)
    Automatic pattern segmentation of jacquard images is a challenging task due to the complexity of the images. Active contour models have become popular for finding the contours of a pattern with a complex shape. However, ...
  • A New Fingerprint Image Segmentation Algorithm Based on ROIO 

    Shi, Zhongchao; Xu, Ke; Wang, Yangsheng (The Eurographics Association, 2004)
    We present a new fast and effective method of fingerprint image segmentation, which is different from traditio-nal methods that usually use some certain features to segment diversified images. Based on the region of ...
  • Optimum Detection of MultiplicativeWatermarks for Digital Images in the DWT Domain 

    Sun, Zhongwei; Feng, Dengguo; Xue, Rui (The Eurographics Association, 2004)
    Watermark detection plays a crucial role in digital watermarking. It has traditionally been tackled using correla-tion-based techniques. However, the correlation-based detection is not the optimum choice when the host media ...
  • Progressive Image Transmission Using Singular Value Decomposition 

    Chang, Chin-Chen; Liu, Yi-Long (The Eurographics Association, 2004)
    There are many progressive image transmission schemes using vector quantization-related schemes, but there are some problems associated with them. First, these schemes need to train a codebook, and this codebook will ...
  • Tetrahedral Adaptive Grid for Parallel Hierarchical Tetrahedrization 

    Takama, Yasufumi; Kimura, Akinori; Tanaka, Hiromi T. (The Eurographics Association, 2004)
    Recent advances in volume scanning techniques have made the task of acquiring volume data of 3-D objects easier and more accurate. Since the quantity of such acquired data is generally very large, a volume model capable ...
  • Image-based Rendering of the AnisotropicBRDF ofWoven Fabrics 

    Takeda, Yuki; Viet, Huynh Quang Huy; Tanaka, Hiromi T. (The Eurographics Association, 2004)
    The reflectance of fabric surface is commonly represented by a 4D bidirectional reflectance distribution function (BRDF). To generate the BRDF from measured data by a gonioreflectometer with 2 degrees of freedom of the ...
  • Door Access Control Using Human Face and Height 

    Zhang, H. X.; Ma, R. H.; Huang, W. M.; Huang, Z. (The Eurographics Association, 2004)
    Access control has much attracted research interest recently. In this paper, we propose a method using human face and height as human trait to recognize a person. We observe that eye location extracted from a human face ...
  • A Training-Based Method for Reducing Ringing Artifact in BDCT-Encoded Images 

    Wang, Guangyu; Wong, Tien-Tsin; Heng, Pheng-Ann (The Eurographics Association, 2004)
    The quantization procedure of block-based discrete cosine transform (BDCT) compression (such as JPEG) introduces annoying visual artifact. In this paper, we propose a novel training-based method to reduce the ringing ...
  • A Novel Quadtree-Structured Scheme for Transmitting Chinese Calligraphy Progressively 

    Chang, Chin-Chen; Li, Chien-Fa; Lin, Iuon-Chang (The Eurographics Association, 2004)
    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 ...
  • Mixing Images and Sketches for Retrieving Vector Drawings 

    Ferreira, A.; Fonseca, M. J.; Jorge, Joaquim A.; Ramalho, M. (The Eurographics Association, 2004)
    Current approaches to content-based retrieval of multimedia data usually rely either on query by example or on sketches of the desired image, but not on both. In this paper, we propose a new query specification scheme, ...
  • Analysis of Inter-Frame Coding Without Intra Modes in H.264 

    Cheng, Yun; Wang, Zhiying; Dai, Kui; Guo, Jianjun (The Eurographics Association, 2004)
    H.264/AVC is a new international standard for video coding which has great advantage of coding efficiency com-pared with other standards. It can save about 50% bit-rate compared with that of the successful prior coding ...
  • A New Approach to Multimedia Information Filtering Based on its Structure 

    Huang, Xiaodi; Yong, Jianming (The Eurographics Association, 2004)
    In information filtering systems, the multimedia documents are sequentially presented to users based on the user relevance values. This paper argues that the presented multimedia documents should be both important and ...
  • Simultaneous Tracking of Multiple Objects for Augmented Reality Applications 

    Yuan, C. (The Eurographics Association, 2004)
    This paper presents an appearance-based image processing and tracking algorithm which is applied in a distributed Augmented Reality (AR) system. The tracker is computer vision based and is capable of simultaneous tracking ...
  • A Component-based Authoring Environment for Creating Multimedia-RichMixed Reality 

    Abawi, Daniel; Dörner, Ralf; Grimm, Paul (The Eurographics Association, 2004)
    Applications that seek to combine multimedia with Mixed Reality (MR) technologies in order to create multimediarich MR environments pose a challenge to authors who need to provide content for such applications. Founded on ...
  • Animating Peer-Level Annotations Within Web-Based Multimedia 

    Bulterman, Dick (The Eurographics Association, 2004)
    The TabletPC is an example of a new generation of user interface device where pen-based manipulation of information is integrated directly into a user s workflow. Using the TabletPC's existing pen and electronic ink systems, ...
  • Remote Raster Image Browsing Based on Fast Content Reduction forMobile Environments 

    Rosenbaum, René; Schumann, Heidrun (The Eurographics Association, 2004)
    Enhanced browsing techniques for digital imagery and small displays facilitate the exploration process of large images often by using new ways to represent the image. Reduction of image content is such an approach mostly ...
