    We propose an approach to protect the copyright of image data. Many watermarking techniques have been proposed to guard the copyright of image data, most of which need to embed the watermark in the cover image. Unfortunately, embedding always results in a reduction of image quality. To achieve the goal of copyright protection without reducing image quality, we incorporate the concept of digital si...

    Metamorphosis between 3D objects is often the transformation between a pair of shapes that have the same topology. This paper presents a new model using Reeb graphs and their contours to create morphing between 3D objects having different topology. The proposed method specifies the correspondence between of the input objects by using the graph isomorphic theory. Then the super Reeb graph, which ha... View full abstract»

    Theoretical frameworks of topological modeling and various potential applications have been proposed by Kunii and his collaborators. However serious applications are still wanted to prove the ubiquitous importance of the topological modeling technology. To accelerate progress in this field we need to pay more attention to design patterns that are to be shared among researchers and developers of to... View full abstract»

    Abstraction is one of the most important concepts in computer science. It has been realized in object oriented programming as the form of class hierarchy. In this paper, new abstraction levels are introduced. This abstraction level can be applied in many fields of computer science, including computer graphics, image processing, database systems and design automation. In this paper the new abstract...

    This article presents methods for unraveling the hypercube and the 4D simplex and obtaining the unravelings that corresponds to the hyper-flattening of their boundaries. These regular polytopes can be raveled back using the methods in an inverse way. The transformations to apply include rotations around a plane (characteristic of the 4D space). All these processes can be viewed using a computer an... View full abstract»

    This paper describes how the web-based visualization can be greatly improved using the function-based shape modeling technique. The improvement is possible because the proposed function-defined VRML shape node allows the content creators to describe any complex models with relatively small functions compared to the large-size polygonal mesh based VRML nodes. These function-defined shapes can be us... View full abstract»

    Generally speaking, genetic algorithms (GAs) can provide global optimal solutions with higher probability. However, compared with conventional approaches, GAs are usually more time consuming. To solve this problem, different parallel GAs (PGAs) have been proposed in the literature. A direct method is to employ many slave processors for individual evaluation, and a master processor to synchronize t... View full abstract»

    Web-log mining is a technique to find "useful" information from access-log data. Typically, association rule mining is used to find frequent patterns (or sequence patterns) of visited pages from access logs and to build users' behavior models from those patterns. In this direction, there exists a difficulty that a human decision-maker must do such data mining process many times under different con... View full abstract»

    In order to support multimedia communication over high speed networks, it is necessary to develop routing algorithms which use for routing more than one QoS parameter. This is because new services such as video on demand and remote meeting systems require better QoS. However, the problem of QoS routing is difficult and to find a feasible route with two independent path constraints is NP-complete. ... View full abstract»

    The hypercube has been widely used as the interconnection network in parallel computers. However, when dealing with the parallel computers of very large scale, the port limitation due to the technology greatly forbid the use of hypercube networks. The hypercube-based SGI Origin2000, a newly developed multiprocessor system, tried to solve this problem by introducing a Cray router. In this paper we ... View full abstract»

    A meta Web search engine first sends a user's search requests to its referenced search engines. The results returned by these search engines are then integrated by one result-integrating algorithm and returned to the user. Query precision, completeness and response speed are directly affected by the choice of result integration algorithm. By analyzing common result-integrating algorithms, this pap...

    This paper discusses a communication model to exchange multimedia messages in a group of multiple processes. Quality of Service (QoS) required by an application has to be supported. In traditional communication protocols like TCP and RTP, a process can reliably deliver messages to one or more than one process, i.e. one-way transmission. In the group communication, a process sends multimedia messag... View full abstract»

    We have developed distributed search engine, called cooperative search engine (CSE), in order to retrieve fresh information. In CSE, a local search engine located in each Web server makes an index of local pages. And, a meta search server integrates these local search engines in order to realize a global search engine. This meta server is single point of failure in CSE. We propose redundancy, of m... View full abstract»

    An ANT is a mobile agent that is capable of solving various kinds of routing and congestion problems in computer networking by continuously modifying routing tables in response to congestion. In a distributed problem solving paradigm, a society of ANTs (each contributing some information) collaborate to solve a larger problem. In recent years, ant-based algorithms were used to solve classical rout... View full abstract»
