Uses “difference” of larger Gaussian from more narrowly-focused central one to reduce noise

Digital Data Processing Biological Vision Processing
*D. Young, “Gaussian masks, scale space, and edge detection,” http://www.cogs.susx.ac.uk/users/davidy/teachvision/vision3.html
Can use Shannon Information Theory to reduce noise
Similar methods suitable for first-stage processing in both biological and digital knowledge discovery
Gaussian Difference of Gaussians

Summary
• Effective knowledge discovery requires an architecture – Multiple representation levels
– Increase abstraction with increasing computational complexity
– Defer complex processing until truly required
• Strong neuromorphic basis; use aspects of brain architecture to inspire computational solution
