27 May 2011 (Friday)Seminar Room, NUS Faculty Club NUS6-7pm: Dinner Talk 7-7.45pm: AGM (Notice View Download) 7.35-9pm: Dinner  Ultra High Resolution Imaging: Viewing the Entire World through a Computer Windowby Eric Yap A typical entry level consumer digital camera has 10-15 million pixels, while those for photomicrography typically have 1-2 million pixels. However, human eyes on a pair of legs can achieve many orders of magnitude greater resolution, which together with 3D stereoscopic vision, provides for visual realism and spatial comprehension in real time. Over the past few years, I have been asking how such biological visual and cognitive systems can be mimicked technologically. Improvements in automated image capture, online data storage and transfer, and intuitive interactive displays are making this possible, as exemplified by Google Earth. I have been experimenting with a low cost home brewed system, comprising panoramic robots, automated stitching software, data storage/compression/transfer servers and interactive display software. Images of 10 billion pixels or more can now be captured and visualized economically. I will illustrate this talk with ultrahigh resolution imagery from recent travel (Hong Kong, Malaysia), local culture and sites, laboratory research (BSL3, animal operating theatre) and microscopic imaging (optical and electron microscopy). I will also demonstrate the equipment, tools and websites that I use. Finally, I hope that these technical advances will inspire new applications and approaches in fields as diverse as pervasive digital education, museum curatorship and librarianship, scientific documentation and forensic analysis. As a prelude, you can explore the panorama of Clarke Quay and the photomicrograph of a cerebellum on this page, and indoor panoramas on the BRETSS home page.
