In this paper a framework for automatic online workflow recognition in industrial environments where the issue of concurrent activities rises, is presented. The framework consists of three main parts: The first part is devoted to detecting activity in specific Regions of Interest (ROIs) of the video sequence. This is effected by separating each frame into ROIs and representing the resulting sub...

How to fuse static and dynamic information is a key issue in event analysis. In this paper, we present a novel approach to combine appearance and motion information together through a top-down manner for event recognition in real videos. Unlike the conventional bottom-up way, attention can be focused volitionally on top-down signals derived from task demands. A video is represented by a collect...

The light stop if produced in hadron colliders in the form of t̃1 ̃̄ t1 pair and decaying through the likely decay chain t̃1 → χ̃b followed by χ̃ → χ̃f f̄ , can mimic closely a top quark event when the mass of the stop is close to that of the top quark. Because of the much lower production rate, the stop event can be buried under the top quark event sample. In order to uncover the stop event, specific...

The dynamic flowgraph methodology (DFM) is a promising way to find the prime implicants of a top event for a dynamic system possibly containing digital subsystems. This paper demonstrates how to express dynamic flowgraph methodology models as logic programs, and top events as queries to those programs, in a natural and comprehensible way. Computation of the logic program lists the prime implica...
