NEW CAMERA TECHNOLLOGY WITH COMPUTER-CONTROLLED ZOOM AND FOCUS CAPABILITIES
13 March 2000 - Carnegie Mellon Universtity

"Eye Vision", as CBS calls it, involves shooting multiple video images of a dynamic event, such as a football game, from multiple cameras placed at different angles. The video streams from these cameras are combined by computer and the resulting images reach viewers in a format that will make them feel as if they are flying through the scenes they see.

Football fans tuning into this year's Super Bowl will be treated to a unique new view of the action during play backs. CBS Television will be presenting them using a new technology co-developed by the network and Carnegie Mellon University computer vision expert Takeo Kanade.

"Eye Vision", as CBS calls it, involves shooting multiple video images of a dynamic event, such as a football game, from multiple cameras placed at different angles. The video streams from these cameras are combined by computer and the resulting images reach viewers in a format that will make them feel as if they are flying through the scenes they see.

The action at Super Bowl XXXV will be captured by more than 30 cameras, each poised some 80 feet above the field at Raymond James Stadium in Tampa, Fla. Each camera, with computer-controlled zoom and focus capabilities, is mounted on a custom-built, robotic pan-tilt head, which can swing the camera in any direction at the command of a computer. These camera heads are controlled in concert so that cameras point, zoom and focus at the same time on the same spot on the field, where some action, touch down or fumble, is occurring.

The system operates in the following way: One of the camera heads is designated as the master camera. A human cameraman operates a movable pan-tilt tripod, attached to a TV screen on which the video from the master camera is constantly displayed. The pan-tilt tripod is equipped with sensors to constantly measure its angle. The master camera head moves by mimicking the motion of the tripod as the camera operator moves it to capture a moving object on the field on his TV screen.

In the meantime, information collected from the master camera's pan-tilt angles, zoom and focus is fed to a computer, which quickly computes the appropriate control signal for each of the remaining cameras. This causes all of them to converge on the same target and capture its image from a variety of angles.

Live action on the football field is continuously captured up to 30 times per second by the video cameras. The video of each camera is synchronized and time stamped so that all the views at the most critical and interesting moments can be played back in sequence, as if a viewer had flown around the action.

Kanade will explain his technology in an interview from Tampa, which will air during the Super Bowl Pre-Game Show. He notes that the "Eye Vision" demonstration that will appear on Super Bowl Sunday is only a small part of this new technology, which he calls "Virtualized Reality," as opposed to virtual reality, and is the product of more than six years of research.

For Virtualized Reality technology to achieve its full impact, the set of captured, multiple video images must be processed beyond the play back. The detailed geometrical information about a scene, the shapes of targets and background, is extracted by computer, which enables a person to choose how to view a scene, even from a perspective that was actually not shot by any camera.

To bring this concept to life, Kanade and his students built a "3D room" equipped with more than 50 video cameras and experimented by filming people involved in a variety of sports activities. He also spun off a company named Zaxel Systems, Inc., for commercialization of the technology. Much of this work can be viewed at the Virtualized Reality Web site: http://www.cs.cmu.edu/afs/cs/project/VirtualizedR/www/VirtualizedR.html

In contrast to virtual reality, in which synthetic environments are created, Virtualized Reality technology, and to a lesser extent, Eye Vision, are based on events taking place in the real world, which are captured and processed by computer manipulation.

"Because our models are derived from real images," Kanade says, "the models look much more real than typical virtual worlds."

Kanade says the output from these multiple cameras shooting a scene together from many angles actually can create totally new views that were not captured by any camera. As this technology develops, he believes it will create a completely new way to view sports and entertainment events. People will be able to customize the perspective from which they watch - e.g. from that of a particular player or the ball.

Kanade is the director of Carnegie Mellon University's Robotics Institute. He has been a leader in the development of video-based vision systems used in the university's autonomous vehicles and exploration robots. His team has developed a vision-based autonomous helicopter, which ultimately may be able to aid in search and rescue operations, fire fighting and inspection tasks. He is also a pioneer in medical robotics and computer-assisted surgery, working with surgeons and medical professionals to develop smart tools capable of performing medical procedures better than a physician or machine could do alone.

Kanade earned his undergraduate and graduate degrees in electrical engineering from Kyoto University, Japan. He has been on the Carnegie Mellon faculty since 1980 and director of the Robotics Institute since 1991. He is a member of the National Academy of Engineering. Most recently he received a $100,000 award from the NEC Foundation for C&C Promotion for "fundamental and broad contributions to the development of multimedia through the advancement of robotics and computer vision."

About: Carnegie Mellon Universtity
The Carnegie Institution of Washington (www.carnegieinstitution.org) has been a pioneering force in basic scientific research since 1902. It is a private, nonprofit organization with six research departments throughout the U.S. Carnegie scientists are leaders in plant biology, developmental biology, astronomy, materials science, global ecology, and Earth and planetary science.

Since its founding in 1900 by industrialist and philanthropist Andrew Carnegie, Carnegie Mellon University has been a pragmatic institution, adapting rapidly to change. In fewer than 100 years it has changed its name three times--each transition marking a milestone in the institution's 20th century evolution.

Whether it was Carnegie Technical Schools, as it was in its first 12 years, Carnegie Institute of Technology, its name from 1912 to 1967, or Carnegie Mellon University, three primary purposes formed its foundation. Throughout this century, Carnegie Mellon has focused on delivering distinctive and first-quality education, fostering research, creativity and discovery, and using the new knowledge created on campus to serve our larger society.

When Arthur A. Hamerschlag served as the school's first president, Carnegie Technical Schools' 12 professors and six administrators sought to educate the sons and daughters of Pittsburgh workers for employment in the region's growing industries.

These educators served the vision of Carnegie by organizing into four faculties: the School of Science and Technology, the School of Fine and Applied Arts, the School of Apprentices and Journeymen, and the Margaret Morrison Carnegie School for Women.

In its earliest years, the institution served primarily part-time and undergraduate students. The faculty, many of whom did not have doctor's degrees, focused on teaching and curriculum development.

But research efforts began as early as 1916 when the Division of Applied Psychology of the Carnegie Institute of Technology developed rating scales for job placement. This rating system was used to classify two million men for placement in the armed forces during World War I. Research bureaus were organized in coal mining, nuclear physics, applied chemistry and metallurgy.

And by granting the nation's first undergraduate degree in drama in 1917, the institution began a tradition of leadership in the arts that spanned the century.

Through research and the education of its students during the administration of President Thomas S. Baker in the 1920s and '30s, the institution began its strong tradition of transferring knowledge and skills to industry and government.

Building on this firm foundation, the administration of President Robert E. Doherty introduced a new approach to education that would be used as a model by similar institutions around the nation. The Carnegie Plan for Professional Education, initiated in 1939-40, required engineering and science students to take a quarter of their courses in a new Humanistic and Social Relations sequence. In addition, its curriculum focused on teaching students problem-solving techniques, a hallmark of the Carnegie Mellon educational experience today.

While the Doherty administration has been credited with this educational innovation, it also oversaw growth in the institution's research capability. Between 1936 and 1950, the number of graduate students grew from 36 to more than 260. The research budget ballooned from $156,000 to $1 million.

In the 1950s, the newly formed Graduate School of Industrial Administration, endowed by William Larimer Mellon, emerged as one of the three or four best business schools in the nation. (In 2004 the school was renamed the David A. Tepper School of Business after benefactor and alumnus David Tepper (MBA '82).) Today, the school is recognized as a pioneer in the field of management science and one of the top business schools in the world.

The Warner administration oversaw the institution's burgeoning research enterprise. This period of research growth was aided by the work of the institution's Computation Center, founded in 1956 to provide computing services to the campus. A major grant from benefactor Richard K. Mellon in 1965 aided the establishment of a Computer Science Department, a department which would be the genesis of Carnegie Mellon's worldwide reputation in computer science.

By the end of the Warner administration and the start of the administration of President H. Guyford Stever in 1966, Carnegie Tech had most elements of a university. Its merger in 1967 with the Mellon Institute created Carnegie Mellon University and brought a $60 million endowment, extensive research facilities and renowned research personnel to the institution.

Five years later, President Richard M. Cyert (1972-90) began a tenure that was characterized by unparalleled growth and development. The university's research budget soared from about $12 million annually in the early 1970s to more than $110 million in the late 1980s. The work of researchers in new fields such as robotics and software engineering helped the university build on its reputation for innovative ideas and pragmatic solutions to the problems of industry and society. Carnegie Mellon began to be recognized as a truly national research university able to attract students from across the nation and around the world.

The Cyert administration stressed strategic planning and comparative advantage, pursuing opportunities in areas in which Carnegie Mellon could outdistance its competitors.

An archetypal example of this approach was the introduction of the university's "Andrew" computing network in the mid-1980s. This pioneering network, which linked all computers and workstations on campus, set the standard for educational computing and firmly established the university as a leader in the uses of technology in education and research.

Education and teaching also benefited in this period with the establishment of a University Teaching Center to improve faculty teaching and the renovation of many of the university's classrooms.

Cognizant of the university's heritage, President Robert Mehrabian (1990-97) invited alumni from the era of the institution's first president, Arthur A. Hamerschlag, to attend his inauguration in 1990. President Mehrabian emphasized Carnegie Mellon's traditional strengths in education, research and service to society while focusing on initiatives for leadership in the 21st century.

With the appointment of the university's first Vice Provost for Education, President Mehrabian placed renewed emphasis early in his administration on the quality of undergraduate education. He also moved aggressively to complete the most ambitious campus building plan since the Warner era. The University Center, which opened in August 1996, and the Purnell Center for the Arts, to be completed by the fall of 1999, are keys to enhancing the quality of life on campus, another priority of the Mehrabian administration.

Confronted by shrinking governmental support of university research, President Mehrabian diversified the university's research agenda. He stressed the need to build strong relationships with the business world, matching industry's needs with the university's areas of research strength. He also put new emphasis on productivity, improvement of administrative services and strategic management of university resources.

President Mehrabian established strong, new partnerships with the greater Pittsburgh community. He led a community-wide economic development initiative, spurred collaboration with primary and secondary schools, and worked closely with local community groups.

On April 15, 1997, Jared L. Cohon, former dean of Yale University's School of Forestry and Environmental Studies, was elected by the university's Board of Trustees to succeed President Mehrabian, who resigned to spend more time with his family in California.

"Since I was chosen, since this wonderful event has occurred, it has made me reflect on why you are choosing me," President Cohon said in his first speech to the university community. "And I've said to people since this was announced that the more I think about it, the more I realize how well I think this institution and I fit together. We'll see if that's true. I think it is.

"When I was at Johns Hopkins we used to always hold up Carnegie Mellon as an example," Cohon said. "So, for many years I've ... been jealous of what has been accomplished here across departmental lines. I celebrate that. I think it is so valuable in every aspect of this university and it will position Carnegie Mellon to be even better...."

During Cohon's presidency, Carnegie Mellon has continued its trajectory of innovation and growth. Today, President Cohon is leading implementation of a comprehensive strategic plan that aims to leverage the university's existing strengths to benefit society in the areas of biotechnology and the life sciences, information and security technology, environmental science and practices, the fine arts and humanities.

The university is also committed to broadening and enhancing undergraduate education to allow students to explore various disciplines while maintaining a core focus in their primary area of study. Realizing that today's graduates must understand international issues, Carnegie Mellon is committed to providing a global education for its students and is striving to expand its international offerings and to increase its presence on a global scale. Increasing diversity, in all aspects, and fostering the economic development of southwestern Pennsylvania, are also top priorities.

Over the years Carnegie Mellon's leaders have reflected Andrew Carnegie's original dedication and commitment to this institution. In his 1900 letter to the mayor of Pittsburgh establishing Carnegie Technical Schools, Andrew Carnegie wrote, "My heart is in the work." These words have been echoed by students, faculty and administrators throughout this century and they live on the Carnegie Mellon campus today.
