    • Estimating Traffic Density Using Sounds of Moving Vehicles 

      Kato, Jien; Hiramatsu, Yoshitaka; Watanabe, Toyohide (The Eurographics Association, 2004)
      This paper proposed a method for automatically estimating traffic density by using sounds of moving vehicles. The approach is based on the idea of recognition of the temporal variations that appear on the power signals ...

    • 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 ...

    • 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, ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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 ...

    • 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, ...

    • 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 ...

    • 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 ...

    • 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 Web Services-Based Architecture for Capability-Aware Ubiquitous Media 

      Haipeng, Wang; Xingshe, Zhou; Zongtao, Duan; Tao, Zhang (The Eurographics Association, 2004)
      Ubiquitous media aims to provide media services anytime and anywhere. To realize it, one challenge is how to provide customized and dynamic services to a variety of computing devices with different capabilities. This paper ...
