Recovering 3D depth information from two or more 2D intensity images is a long standing problem in the computer vision community. This paper presents a multi-baseline, coarse-to-fine stereo algorithm which utilizes any number of images (more than 2) and multiple image scales to recover 3D depth information. Several "view-selection strategies" are introduced for combining information across the ...

While it is widely known that port scanning is widespread, neither the scanning landscape nor the defensive reactions of network operators have been measured at Internet scale. In this work, we analyze data from a large network telescope to study scanning activity from the past year, uncovering large horizontal scan operations and identifying broad patterns in scanning behavior. We present an a...

Cyber security threats are still big concerns of the cyber world. Even though many defense techniques have been proposed and used so far, the antivirus (AV) software is very widely used and recommended for the end-usersPC community. Most effective AV products are commercial and thus competitive and it is not obvious for security researchers or system developers how exactly the AV works or how i...
