The BLUR Project 2
Blur
• No, not remove it … add it !
• Real optics
![Page 3: .1 The BLUR Project Brian A. Barsky University of California, Berkeley.](https://reader036.fdocuments.in/reader036/viewer/2022070404/56649f395503460f94c56409/html5/thumbnails/3.jpg)
The BLUR Project 3
Importance of Blur
• Real images are rarely in perfect focus• Perfectly sharp computer generated images appear
fake• Control over what is and is not in focus is a vital
photographic tool• Depth of Field (DOF)

The BLUR Project 14
Fast and Realistic Blurring
Our new class of methods exploits coherence of the underlying four dimensional tensor structure of the blur operator

The BLUR Project 16
Optometry and Ophthalmology• Simulate actual patient vision • Simulate visual disorders to
doctors • Show potential problems
with corneal surgery to candidates
• Simulate actual vision using pre- and post-op wavefront aberrometry data
• Show predicted vision by using modeled wavefront measurements
