In this paper a novel unsupervised segmentation framework for texture image queries is presented. The proposed framework consists of an unsupervised segmentation method for texture images, and a multi-filter query strategy. By applying the unsupervised segmentation method on each texture image, a set of texture feature parameters for that texture image can be extracted automatically. Based upon these parameters, an effective multi-filter query strategy which allows the users to issue texture-based image queries is developed The test results of the proposed framework on 318 texture images obtained from the MIT VisTex and Brodatz database are presented to show its effectiveness.

There are those who now think that traditional library services, such as cataloging and reference, will no longer be needed in the future, or at least will be fully automated. Others are equally adamant that human intervention is not only important but essential. Underlying such positions are a host of assumptions - about the continued existence and place of paper, the role of human intelligence and interpretation, the nature of research, and the significance of the human element. This panel brings together experts in libraries and digital technology to uncover such issues and assumptions and to discuss and debate the place of people and machines in cataloging and reference work.

International Conference on Intelligent Transportation

作者： Shu-Ching Chen Mei-Ling Shyu Chengcui Zhang Distributed Multimedia Information System Laboratory School of Computer Science Florida International University Miami FL USA Department of Electrical and Computer Engineering University of Miami Coral Gables FL USA

Recently, the Intelligent Transportation systems (ITS) have been identified as the new paradigm to address the growing mobility problems, and to alleviate congestion and augment the quality of vehicular flow. This paper presents an intelligent and automatic framework for spatio-temporal vehicle tracking in video sequences in order to provide useful information to the traffic control center. The spatio-temporal relationships of the objects are captured automatically via a proposed unsupervised image/video segmentation method and multimedia input strings. A traffic video sequence is used to demonstrate the effectiveness of the proposed framework to identify and track the vehicle objects in the video sequence.

A kinematic modeling method is proposed which uses augmenting variables to match the dimensions of the input vector and output vector of each serial subchain of the mobile robots. Firstly, kinematic models of various type of wheels are derived including skidding and sliding velocities. Then the method of augmented generalized coordinates is applied to obtain inverse and forward kinematic models. The kinematic models derived by the direct inverse of the augmented matrices provide an accurate solution, which was not achievable by the modeling method based on the pseudo-inverse method which provides an approximate solution. Lastly, two kinematic models for typical, differential-driven mobile robots are presented to show the effectiveness of the proposed modeling method.

In this paper a three dimensional (3D) image processing expert system called 3D-IMPRESS is presented. This system can automatically construct a 3D image processing procedure by using pairs of an original input image and a desired output figure called sample figure given by a user This paper describes the outline of 3D-IMPRESS and presents a method of procedure consolidation for generating a procedure commonly applicable to some other 3D gray images. Finally, we show segmentation results of 3D chest CT images by using the procedures generated by 3D-IMPRESS and discuss the performance of the system. © 2001 IEEE.

We present a framework that allows applications to build and customize VM services on the LA microkernel. While the LA microkernel's abstractions are quite powerful, using these abstractions effectively requires higher-level paradigms. We propose the dataspace paradigm which provides a modular VM framework. The modularity introduced by the dataspace paradigm facilitates implementation and permits dynamic configurability. Initial performance results from a prototype are promising.

A PARALLEL DECOUPLING TECHNIQUE TO ACCELERATE CONVERGENCE OF RELAXATION SOLUTION OF INTEGRAL-DIFFERENTIAL-ALGEBRAIC EQUATIONS

In this paper, we first study the covergence performance of relaxatio-based algorithms for linear integral differential-algebraic equations (IDAEs), then a parallel decoupling technique to speed up the convergence of the relaxation-based algorithms is derived. This novel technique is suitable for implementation of parallel processing for complicated systems of IDAEs. Factors taking effect on the performance of parallel processing are discussed in detail. Large numerical examples running on a network of IBM RS/6000 SP2 system are given to illustrate how judicious partitionings of matrices can help improve convergence in parallel processing.

In order to reach an object, we need to solve the inverse kinematics problem, i.e., the coordinate transformation from the visual coordinates to the joint angle vector of the arm. The learning of the inverse kinematics model for calculating every joint angle that would result in a specific hand position is important. However, the inverse kinematics function of the human arm is a multi-valued and discontinuous function. It is difficult for a well-known continuous neural network to approximate such a function. In order to overcome the discontinuity of the inverse kinematics function, a novel modular neural network architecture is proposed in this paper. © 2001 Published by Elsevier science B.V.

This paper describes a TV program generation system using digest video scenes that are retrieved from video streams with the program indexes. The key features of the system are: (1) TV programs can be dynamically generated from digest video scenes selected by user preference. (2) Directions can be added using a happiness or sadness level based on the user preferences. (3) Personalized TV programs for an individual viewer can be made. The procedures taken by the system are as follows: (1) Conjunctive expressions between scenes are automatically generated; (2) Emotional expressions are automatically generated by user preference; (3) TV program metaphors are defined; (4) Direction templates corresponding to the metaphors are defined; (5) These expressions and definitions are coded using a markup language, and (6) Contents such as virtual characters and movies are synchronized. The resultant program can be shown on a TV set.
