We present a novel spatiotemporal saliency model for object detection in videos. In contrast to previous methods focusing on exploiting or incorporating different saliency cues, the proposed method aims to use object signatures which can be identified by any kinds of object segmentation methods. We integrate two distinctive saliency maps, which are respectively computed from object proposals of an...
In cache-based side channel attacks, a spy that shares a cache with a victim probes cache locations to extract information on the victim's access patterns. For example, in evict+reload, the spy repeatedly evicts and then reloads a probe address, checking if the victim has accessed the address in between the two operations. While there are many proposals to combat these cache attacks, they all have...
Cache-based covert channel attacks use highly-tuned shared-cache conflict misses to pass information from a trojan to a spy process. Detecting such attacks is very challenging. State of the art detection mechanisms do not consider the general characteristics of such attacks and, instead, focus on specific communication protocols. As a result, they fail to detect attacks using different protocols and,...
The research of facial beauty is an interdisciplinary topic involved in psychology, aesthetics, computer version and machine learning. In this paper, we propose several methods to assess facial beauty under unconstrained conditions. Our main works are as follows: First, we apply the local binary pattern (LBP) descriptor in different bins for face representation. We tried different types of LBP methods...
Traffic patterns, varying from applications, have great influence on the performance of on-chip network. We observed there exists some balanced traffic, almost distributing traffic load evenly around the whole network. Such traffic pattern makes optimization highly intractable. General optimization method, including modifying the structure of routers and topology, disappointedly, can't give satisfactory...
