As a type of stereo images, anaglyphs can be displayed not only on the screen, but are currently the only solution of stereo images that can be displayed on paper. However, its deficiencies, like retinal rivalry and color distortion, could cause visual fatigue. To address this issue, an algorithm is proposed for anaglyph generation. Unlike previous studies only considering one aspect, it considers both retinal rivalry and color distortion at the same time. The algorithm works in the CIE <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <msup> <mrow> <mtext>L</mtext> </mrow> <mrow> <mo>∗</mo> </mrow> </msup> <msup> <mrow> <mtext>a</mtext> </mrow> <mrow> <mo>∗</mo> </mrow> </msup> <msup> <mrow> <mtext>b</mtext> </mrow> <mrow> <mo>∗</mo> </mrow> </msup> </math> color space and focuses on matching the perceptual color attributes especially the hue, rather than directly minimizes the sum of the distances between the perceived anaglyph color and the stereo image pair. In addition, the paper builds a relatively complete framework to generate anaglyphs so that it is more controllable to adjust the parameters and choose the appropriate process. The subjective tests are conducted to compare the results with several techniques which generate anaglyphs including empirical methods and computing methods. Results show that the proposed algorithm has a good performance.}, journal={WIRELESS COMMUNICATIONS & MOBILE COMPUTING}, author={Qi, Min and Cui, Shanshan and Du, Qianmin and Xu, Yuelei and McAllister, David F.}, year={2021}, month={Sep} }

We extend the monoscopic statistical rain models to simulate the behavior and distribution of falling rain for stereo viewing. Our goal is to be able to render in real-time frame rates. In this investigation we ignore the complex issues of scene illumination and concentrate on the parameters that produce a realistic rain distribution. Using the concept of retinal persistence we render a visible falling raindrop as a linear streak. To speed rendering we use pre-computed images of such rain streaks. Rain streak positions for the left- and right-eye views are created by generating random numbers that depend on the view volume of the scene. We permit interactive but controlled modification of rain parameters such as density and wind gusts. We compare our approach to the use of existing 2D-3D conversion methods. The results demonstrate that using commercial 2D-3D converters are not sufficient in producing realistic stereo rain effects. Future research will concentrate on including complex lighting interactions.}, journal={STEREOSCOPIC DISPLAYS AND APPLICATIONS XXIV}, author={Hussain, Syed A. and McAllister, David F.}, year={2013} }

The method depends upon knowing the RGB spectral distributions of the display device and the transmission functions of the filters in the viewing glasses. It requires the solution of a nonlinear least-squares program for each pixel in a stereo pair and is based on minimizing color distances in the CIEL*a*b* uniform color space. The method is compared with several techniques for computing anaglyphs including approximation in CIE space using the Euclidean and Uniform metrics, the Photoshop method and its variants, and a method proposed by Peter Wimmer. We also discuss the methods of desaturation and gamma correction for reducing retinal rivalry.}, journal={STEREOSCOPIC DISPLAYS AND APPLICATIONS XXI}, author={McAllister, David F. and Zhou, Ya and Sullivan, Sophia}, year={2010} }

Multiple VR programs for children aged 2 to 9 were built and tested between 1992 and 2007. Based on these results, a learning design evolved that uses practice in virtual space with guidance and correction by an animated character, strategic limitations on allowed actions to force correct patterning, and customization of worlds and responses to simplify user controls. This article describes program evolution by comparing design details and results as variations in behavioral responses between disorders, differences in skill set complexity between different safety skills being taught, and improved technology required changes in the virtual training methodology. A series of research projects are summarized in which the VR programs proved effective for teaching children with ASD and FASD new skills in the virtual space and, where measured, most children generalized the actions to the real world.}, number={3}, journal={TOPICS IN LANGUAGE DISORDERS}, author={Strickland, Dorothy C. and McAllister, David and Coles, Claire D. and Osborne, Susan}, year={2007}, pages={226–241} }

By analysing ‘isolexemic’ sequences, the method addresses the issues of very short criminal exemplars and the need for open-set identification. An algorithm is given that computes an average spectral shape of the speech to be analysed for each glottal pulse period. Each such spectrum is converted to a probability density function and the first moment (i.e. the mean) and the second moment about the mean (i.e. the variance) are computed. Sequences of moment values are used as the basis for extracting variables that discriminate among speakers. Ten variables are presented all of which have sufficiently high inter- to intraspeaker variation to be effective discriminators. A case study comprising a ten-speaker database, and ten unknown speakers, is presented. A discriminant analysis is performed and the statistical measurements that result suggest that the method is potentially effective.

This is without the use of text, speech recognition or mechanical or other sensing devices attached to the speaker's mouth. This capability can reduce the time required for mouth animation considerably. We expect it to be competitive eventually with the speech/text driven solutions which are becoming popular. Our technique would require much less interaction from the user and no knowledge of phonetic spelling. We discuss the problems of producing an algorithm that is speaker independent. The goal is to avoid having to measure mouth movements off video for each speaker's training sounds. We have discovered that eliminating variation due to pitch yields moments which are mouth shape dependent but not speaker dependent. This implies that careful construction of predictor surfaces can produce speaker independent prediction of mouth motion for English vowels.}, number={20-21}, journal={COMPUTER NETWORKS AND ISDN SYSTEMS}, author={McAllister, DF and Rodman, RD and Bitzer, DL and Freeman, AS}, year={1998}, month={Nov}, pages={1975–1980} }
