Summer Research Grants in the VDIL
Researchers from various disciplines have been working in the Video and Digital Imaging Lab (VDIL) on their summer grant projects. The following is a brief description of each project.

Steve Hilyard will be showing a one-man exhibition of artwork at the Tweed Museum in the fall of 2001. He plans to create three of the pieces for the show in the VDIL during the summer. The first will involve scanning photographic images then digitally manipulating them. The second will take the form of very large-scale digital drawings. This will require that he develop techniques for the creation of complex vector files by working back and forth between AutoCAD and Illustrator. He will use the plotter in the VDIL to make proofs before an outside vendor prints the final images with a larger machine. The third piece will be a digital animation with soundtrack, made using Bryce 4 and Media 100. This piece will be mastered to DVD by an outside vendor. He completed an animation in the VDIL last summer that will also be a part of the show. This animation needs to be edited in Media 100 before it too is mastered to DVD.

Gene Ley provides training and quality control services for health surveys conducted by the National Institutes for Health. The multimedia programs he develops for training and quality control often require embedding audio, video and graphic clips into the programs.

Bill Payne's project will involve completing an edit of a three-camera shoot we did of THE BACCHAE. He hopes to begin editing the show together this semester but doesn't expect to finish. He is in the beginning stages of developing the next live stage piece that will incorporate video generated in the VDIL. He sees this long-range project happening sometime in the 2003-04 school year. He will research how video has been integrated into live theatre around the world. He will also be gathering information about theatres and artists that have utilized video in live stage performances, the technology they use, the design process they have found most effective, and some of the aesthetic choices they have made. He believes coupling this current editing project with the beginnings of more in depth research on the state of the art in the field will enhance the next project.

Catherine Ishino will pursue finishing up the editing of the rest of her relatives' first person oral histories on their World War II Internment experience. She'd like to add to her 15 minute interviews to create an hour video piece for web distribution. Also, in the long term, she wants to try to connect her documentary to other first person oral histories, which are being interconnected on the web

Alexis Pogorelskin will complete digital editing for a video documentary of approximately 58 minutes in length. The subject concerns Karelian fever that is the recruitment of North American Finns to the Karelian region of the USSR in the early 1930s. She has conducted extensive video interviews for this project. She has photos, archival material, and period music, all of which will be combined in video form, using the latest digital editing technology. Numerous grants from the Univ. of Minn. and the Minn. Historical Society have supported the research for this project in Finland and Russia. She has published extensively on this topic and has completed a web site on it using the facilities of the VDIL.

Matthew Andrews' summer project will focus on studying proteins in cerebrum and brainstem tissues that will be compared with one another in terms of their protein profiles. Total and/or fractionated proteins will be prepared and separated by two-dimensional electrophoresis (2D-PAGE). Isolating the proteins and separating them first by their respective iso-electric points, then separating in a second acrylamide gel on the basis of size is the method to isolate proteins. These 2D gels from both active animals and hibernators will be electrophoretically separated and analyzed by examination of stained spots corresponding to individual proteins. A comparison of the gels using flatbed scanners and software in the Visualization and Digital Imaging Lab (VDIL) will allow the researchers to superimpose images revealing whether certain proteins are present in a hibernator versus an active animal. Digital imaging is a necessary and fundamental part of the analysis portion of the project since advanced imaging methods allow archiving and analysis of protein expression profiles. Differentially expressed proteins will be excised from the gel and sequenced by the University of Minnesota mass spectroscopy facility in St. Paul, Minnesota. Once sequenced, the proteins found will add insight into their function in the hibernating animal.

Paul Kiprof's summer project will extend the studies of cage structures to other organic carbocations, which are stabilized by oxygen bonded to the carbon, the so-called carboxonium ions. Due to their unrestricted structure and the oxygen atom interaction, they have more ways to stabilize themselves. A comparison between cage-structures and unrestricted carboxonium ions will lead to a better understanding of the differences in their chemistry but also point out similarities they have.

Allen Mensinger's research will investigate regeneration of the seventh (VIIth) nerve through a sieve microelectrode in the walleye, Stizostedion vitreum. The VIIth nerve is the anterior lateral line nerve (ALLN), which innervates the canal and superficial neuromasts of the cephalic lateral line system in fish. Previous research has shown success with the regeneration of the VIIIth nerve, innervating the vestibular and auditory system, through a sieve microelectrode (Mensinger et al. 2000). The current study focuses on the VIIth nerve because fish use the lateral line to gather information about their natural environment and this information shapes the behavior and ecology of the animal.

The main objective of Mohammed Hasan's project is to design an automatic system for detection, recognition and model-based coding of faces for applications such as automatic face recognition and database image compression. The main process in the implementation of this system consists of Karhunen-Loeve (eigenspace) based feature extraction whose output is used for both recognition and coding. This leads to a compact representation of the face that can be used for both recognition as well as image compression.
