Malvar's lecture from the end of September was recently added to the MIT World archive. It runs 76 minutes and focuses on reent advances in digital processing of images and audio.
Henrique [Rico] Malvar hopes to impress a tough crowd with “tricks” hot from Microsoft’s research labs. His show-and-tell features the latest magic in sound and image digital signal processing, soon to appear on your PC or laptop...Malvar’s got high expectations for breakthroughs from the image processing labs. “I hope these will affect everybody’s lives,” he says. Malvar unveiled “image stitching” software that can automatically create panoramas from a bunch of unaligned pictures of a common theme. New software can also merge different photographs of the same subject into a single shot by “taking the best part of each one.” Bye-bye red eye. There’s also Malvar’s Big Picture application, which can automatically meld hundreds of photos of some environment “to create a humongous panorama” in which one can delve at the finest of resolutions. He demonstrated this using a photograph of the entire Seattle cityscape, into which he zoomed to discover a pair of worker’s green gloves lying atop a skyscraper work site.
The piece de resistance was “Photosynth,” recently released on the web, which enables disparate users to piece together “group images that share a context” into a single, three-dimensional image. Imagine hundreds of separate tourist photos of a famous site like St. Peter’s Square, assembled into an organized whole by a digital higher power.
