    There is an increasing need for application-based private network design. Major mismatches exist between traditional traffic input and application-based traffic input with a large design variety of private networks. The authors discuss a new traffic engineering concept for inter-LAN traffic and define a new system model for consultation-oriented network design. Three server interface points, model based interface, application based interface, node based interface, are compared from the engineering requirements. The advantages of node based interface in end user friendliness and extensibility are shown. A GUI with node based interface concept is presented.

  • A Study on evaluating technique for artifacts of converted images by motion compensated standards converters

    This paper considers the artifacts which are generated by motion compensated standards converters. The artifacts are divided between motion burr and isolated artifacts. Furthermore, in this paper, the two values are proposed for evaluating the those two artifacts. One value for motion burr depends on field difference values, and the other value for isolated artifacts depends on values of the fourier domain. Performance of those values are confirmed by the simulation test for some converted images which are converted by some kind of converting algorithms and some block sizes for estimating motion vectors.

    Many numbers of Golay code are able to use overlapping for spurious responses cancelled mutually. For example, an image screen is divided into 4 blocks. In case of a histgram pattern of each block concentrates in the some domain, the same Huffman code is used in each block. Transmission signal is decreased by the product of the sequance of the Golay and Huffman code. Two examples, one dimensional signal such as facsimile and two dimensional image signal are discussed.

    In our virtual space teleconferencing system, in order to detect facial expressions and to reconstruct 3-D facial images, 3-D markers are attached to the face and traced visually. For the reconstruction of facial expressions, the tracing results are used to control the nodes of the wire frame model. In this paper, we explain the marker tracing system which consists of a CCD camera, a marker tracing device, and a personal computer. Markers are traced by this system at the sending site. Also we explain the facial image reconstructing system at the receiving site.
