Masked Queries for Search Accuracy in Peer-to-Peer File-Sharing Systems
Peer-to-peer file-sharing systems suffer from the overspecification of query results due to the fact that queries are conjunctive and the descriptions of shared files are sparse. ...

Scale Adaptive Filtering Derived from the Laplace Equation
In this paper, we present a new approach to scale-space which is derived from the 3D Laplace equation instead of the heat equation. The resulting lowpass and bandpass filters are...

Example-Based Learning for Single-Image Super-Resolution
Abstract. This paper proposes a regression-based method for singleimage super-resolution. Kernel ridge regression (KRR) is used to estimate the high-frequency details of the underl...

Structured pursuits for geometric super-resolution
Super-resolution image zooming is possible when the image has some geometric regularity. We introduce a general class of non-linear inverse estimators, which combines linear estima...
