Family of PRGs based on Collections of Arithmetic Progressions
Arithmetic progression sequence pseudorandom number
2017/4/19
In security analysis, we study the difficulty of the inverse problem of recovering the seed pair from the keystream of the proposed method(s). Based on this study, we deduce a lower bound on the sizes...
Multiscale Shape and Detail Enhancement from Multi-light Image Collections
image enhancement NPR relighting shape depiction bilateral filter multiscale image processing
2016/5/24
We present a new image-based technique for enhancing the shape
and surface details of an object. The input to our system is a small
set of photographs taken from a fixed viewpoint, but under varying...
Interactive 3D Architectural Modeling from Unordered Photo Collections
Photo Collections Architectural Modeling
2016/5/24
We present an interactive system for generating photorealistic, textured,
piecewise-planar 3D models of architectural structures and
urban scenes from unordered sets of photographs. To reconstruct

Learning to Rank Answers to Non-Factoid Questions from Web Collections
Web Collections Non-Factoid Questions
2015/9/9
This work investigates the use of linguistically motivated features to improve search, in particular for ranking answers to non-factoid questions. We show that it is possible to exploit
existing larg...
Learning Dependency Translation Models as Collections of Finite-State Head Transducers
Translation Models Finite-State Head Transducers
2015/8/25
The paper defines weighted head transducers, finite-state machines that perform middle-out string
transduction. These transducers are strictly more expressive than the special case of sta...
Scientists, like most people, are instinctive collectors. The founders of Scripps Institution of Oceanography were no exception. As they began exploring the marine realm in the vicinity of the fledgli...
