pandemic preserving animal specimens natural history collections
2021/1/28
It's been more than a year since the first cases were identified in China, yet the exact origins of the COVID-19 pandemic remain a mystery. Though strong evidence suggests that the responsible coronav...
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...
