LIMSI @ MediaEval SED 2014
This paper provides an overview of the Social Event Detection (SED) system developed at LIMSI for the 2014 campaign. Our approach is based on a hierarchical agglomerative clustering that uses textual metadata, user-based knowledge and geographical information. These different sources of knowledge, either used separately or in cascade, reach good results for the full clustering subtask with a no...
متن کاملSingle - Electron Device ( SED )
The research on single-electron devices (SEDs) [1] has already spanned a long history. It started with metal or superconductors in the late 80s [2, 3] and then expanded to semiconductors [4-6] in the 90s. Room-temperature operating silicon based devices [7-9] activated the research from the viewpoints of LSI application, and there have been many studies focusing on both device fabrication and c...
متن کاملSurveillance Event Detection (SED)
We report on our system used in the TRECVID 2013 Multimedia Event Detection (MED) and Multimedia Event Recounting (MER) tasks. For MED, it consists of four main steps: extracting features, representing features, training detectors and fusion. In the feature extraction part, we extract more than 10 low-level, high-level, and text features. Those features are then represented in three different w...
متن کاملEvent detection: BJTU-SED at Trecvid 2011
In trecvid 2011, our team takes part in 2 event detection competition including pointing and cell to ear. We build two systems to recognize these events separately. For pointing, we extract texture and silhouette to recognize this action. And for cell to ear, we use orientation of optical flow and SVM classifier to finish this work.
متن کاملSED modeling of Young Massive Stars
In this contribution, I review the applications and potential limitations of the spectral energy distribution fitting tool that I have developed, with a strong emphasis on the limits to which this tool can be used to improve our understanding of massive star formation. I discuss why our current grid of models cannot be used to distinguish between the several competing theories of massive star f...
