PPT-On the Smoothing Parameter of a Lattice

Daniel Dadush Centrum Wiskunde amp Informatica CWI Joint work with KM Chung FH Liu and C Peikert Outline Lattice Parameters Hard Lattice Problems Worst Case to Average Case Reductions. Our method suppresses low amplitude details Mean while it globally retains and sharpens salient edges Even the highcontrast thin edges on the tower are preserved Abstract We present a new image editing method particul arly effective for sharpening m June 2012, Planetary Mappers Meeting. Smoothing Contacts. What is smoothing:. Smoothing allows you to add curvature to linework making it . arcuate. instead of straight between vertices. Why you should smooth:. Smoothing Smoothing • F (smoothing) could be implemented by energy minimization • D ifferent energy functions can be used for different approaches • T he most frequent function is the Sparsification. and the Approximate Closest Vector Problem.
