Predictor Surfaces for Lip Synchronization Animation of Voiced Input (2008)

Rika Krothapalli, David F. Mcallister, Robert D. Rodman, Donald Bitzer, Meng Wang, Jamie Taylor

The authors are producing two-dimensional animated human faces with lip motion synchronized to a given speech sound file. The process is called lip synchronization. We assume the only input is the...

Electronic Imaging ‘07 Real-time photorealistic stereoscopic rendering of fire (2008)

Benjamin M. Rose, David F. Mcallister

We propose a method for real-time photorealistic stereo rendering of the natural phenomenon of fire. Applications include the use of virtual reality in fire fighting, military training, and...

A Practical Implementation of Maximum Likelihood Voting (2007)

Kalhee Kim, Mladen A. Vouk, David F. Mcallister

The Maximum Likelihood Voting (MLV) strategy was recently proposed as one of the most reliable voting methods. The strategy determines the most likely correct result based on the reliability history...

Fault-Tolerant Software Voters Based on Fuzzy Equivalence Relations (2007)

Kalhee Kim, Mladen A. Vouk, David F. Mcallister

Redundancy based fault-tolerant software strategies frequently use some form of voting to decide which of the answers their functionally equivalent versions produce is "correct." When...

Realtime stereo imaging of gaseous phenomena (2005)

Tyler M. Johnson, David F. Mcallister

Gaseous phenomena such as clouds, fog, and mist have been difficult to render in realistic monoscopic imaging environments. Such phenomena are transparent, cast shadows, have dynamic behavior, and...

Producing Anaglyphs from Synthetic Images (2003)

William Sanders, William S, David F. Mcallister

Distance learning and virtual laboratory applications have motivated the use of inexpensive visual stereo solutions for computer displays. The anaglyph method is such a solution. Several techniques...

A TASK-BASED FRAMEWORK FOR THE QUANTITATIVE EVALUATION OF INPUT DEVICES (2003)

David F. Mcallister, Martin S. Dulberg

This research describes the development of a conceptual framework and methodology that will permit the evaluation of input devices in graphical user interfaces in a more meaningful context than...

Real-Time Image-Based Rendering for Stereo Views of Vegetation (2002)

Jitendra A. Borse, David F. Mcallister

Rendering of detailed vegetation for real-time applications has always been difficult because of the high polygon count in 3D models. Generating correctly warped images for nonplanar projection...

Speaker Independence in Automated Lip-sync for Audio-video Communication (1998)

David F. Mcallister, Robert D. Rodman, Donald L. Bitzer, Andrew S. Freeman

By analyzing the absolute value of the Fourier transform of a speaker’s voice signal we can predict the position of the mouth for English vowel sounds. This is without the use of text, speech...

An Empirical Evaluation of Consensus Voting and Consensus Recovery Block Reliability in the Presence of Failure Correlation (1993)

David F. Mcallister, David E. Eckhardt, Kalhee Kim, Mladen A. Vouk, Mladen A. Vouk

The reliability of fault-tolerant software system implementations, based on Consensus Voting and Consensus Recovery Block strategies, is evaluated using a set of independently developed functionally...

Modeling Execution Time of Multi-Stage N-Version Fault-Tolerant Software (1992)

Mladen A. Vouk, Amitkumar M. Paradkar, David F. Mcallister

An N-version system can be subdivided into stages for the purpose of forward error recovery through voting after each stage. In the simplest case at each stage the whole system waits for the slowest...

Rotation algorithm artifacts in stereoscopic images (1991)

Hodges, Larry F., McAllister, David F.

We examine the effect of using rotations for generation of the left- and right-eye perspective views of a stereoscopic image. We show that this approach to stereoscopic display of perspective views...

Analysis of Faults Detected in a Large-Scale Multi-Version Software Development Experiment

Mladen A. Vouk, Alper K. Caglayan, David E. Eckhardt, David F. McAllister, James L. Walker, ...

Twenty programs were built to the same specification of an inertial navigation problem. The programs were then subjected to a three phase testing and debugging process: an acceptance test, a...
