These applications commonly use a mouse as an input device. However, with a single mouse, we can only input two-dimensional coordinates and press mouse buttons for input. Therefore, this conventional input method using a single mouse handled by one hand is not sufficient to support complex or parallel operations in sophisticated applications. On the other hand, it is widely recognized that using two different input devices handled by two hands is useful for complex operations. In this paper, we show our design and implementation of a multipurpose interface which integrates two mice as input device for window system.","PeriodicalId":261724,"journal":{"name":"2001 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (IEEE Cat.

Automatic repeat request (ARQ) is a very popular protocol for error correction. However, long propagation delays and high packet error-rates make long total packet delays. If the received packet has a longer delay than the allowable delay then it will be lost. This loss reduces the quality of the multimedia applications. To solve this problem, an adaptive protocol relay capability is proposed. Having this capability allows the protocol to be adaptively terminated at the relay nodes. However, the error correction between the protocol relay nodes still requires a small delay. We analyze the relationship between the protocol relay capability and the total loss of media transmissions with allowable delay. Also, the criteria for this adaptive protocol relay is described.","PeriodicalId":261724,"journal":{"name":"2001 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (IEEE Cat.

A fundamental problem in stereovision is to find corresponding pixels, points, or other features in both the left and right images that are taken from stereo cameras. For precise measurement and correct matching of repetitive patterns, a multiple-baseline stereo (MBS) algorithm has been proposed (see Kanade, T., ARPA Image Understanding Workshop, p.549-58, 1994; Jeon, J., \"A robust stereo matching technique using multiple cameras\", Ph.D. Dissertation, Chosun University, Korea, 2001). We develop a robust multiple-baseline stereo (RMBS) algorithm to solve continuous, as well as repetitive, multiple local minima through an adaptive window. Experimental results with both synthetic and natural scenes demonstrate that RMBS is faster in processing speed than MBS by 24.1%. In addition, the proposed RMBS algorithm is robust to different types of multiple local minima.","PeriodicalId":261724,"journal":{"name":"2001 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (IEEE Cat.

At-the-disk executed application code is written in a stream-based language that enforces code security and bounds the code's memory requirements. The SmAS disk's system software provides basic support for process scheduling and memory management.

By adopting a pole-zero approach, this model overcomes the limitation of the absence of zeros in the LPC model, which is based entirely on an all-pole AR model for the representation of the vocal tract. Therefore, a more natural synthesized speech can be achieved using this ARMA approach, especially in speech signals that contain nasal, fricative and plosive sounds. The structure of the ARMA lattice model is numerically stable, which is desirable for robust speech synthesis applications. Simulation results indicate that the quality of the synthesized speech of spoken sentences is encouraging, and a better result can be achieved by optimizing the parameters to be used.","PeriodicalId":261724,"journal":{"name":"2001 IEEE Pacific Rim Conference on Communications, Computers and Signal Processing (IEEE Cat.
