Infinite Zooming with Gigapixel Visualization

This lecture explores the motivation behind infinite zooming, as well as the techniques used in Seadragon's DeepZoom, Gigapan, and Photosynth. It also introduces the whereRU Virtual Experience of Rutgers. The second part of the lecture focuses on augmented reality, including its definition, visualization approaches, and possible applications such as advertising, complex tasks support, navigation devices, military and emergency services, prospecting, architecture, sightseeing, collaboration, entertainment, and education. The lecture concludes with tools and links for further exploration.

  1. Lecture 8 Gigapixel Visualization • Motivation • “Infinite Zooming”: Seadragon DeepZoom • Gigapan: stitching multiple images into image pyramid • Photosynth: linking images based on pattern matching • whereRU: Virtual Experience of Rutgers • Tools, Links and Definitions Augmented Reality • Definition • Visualization Approaches • Applications • Tools and Links

  2. Infinite Zooming” – Seadragon’s DeepZoom http://seadragon.com/

  3. Gigapan – stitching multiple images into image pyramid Gigapan Google Earth  “Streetview” Anywhere

  4. Photosynth – linking images based on pattern matching http://whereru.rutgers.edu/photosynth.html whereRU: Virtual Experience of Rutgers using Gigapans & Photosynths

  5. Tools & Links Photosynth site Gigapan site 360citiessite Krpanosite whereRU site Definitions: Gigapixel | Zoomable Interfaces | Map Projections

  6. Augmented Reality – Definition Combines of computer-generated imagery with physical real-world environment • Superimpose imagery In Real-time, Interactive and 3DRegistered • Ability to Track User using Computer Vision and Sensors http://en.wikipedia.org/wiki/Augmented_reality http://www.howstuffworks.com/augmented-reality.htm

  7. Augmented Reality – Visualization Approaches • Overlay Displays in Mobile Devices • Head-Mounted Displays • Virtual Retinal Displays

  8. Augmented Reality – Possible Applications • Advertising: promote a new product via an interactive, web-based AR application. • Support Complex Tasks:assembly, maintenance, and surgery can be simplified by inserting additional information into the field of view. • Navigation Devices: head-up displays used in fighter jets. • Military and Emergency Services:wearable systems to provide information such as instructions, maps, enemy locations, and fire cells. • Prospecting:in hydrology, ecology, and geology, AR can be used to display an interactive analysis of terrain characteristics. • Architecture:simulate planned construction projects. • Sightseeing:show places as they previously existed. • Collaboration:conferences with real and virtual participants. • Entertainment and Education:virtual objects in museums, theme park attractions and games.
