The authors propose a video fingerprinting method based on structural similarity and a graph model. Structural similarity-based fingerprint generation and double-layer matching are the two main contributions. The video is mapped to a graph with frames as its vertices, and structural similarity is proposed to compute the weights of the edges. Then, the fingerprint consisting of a match tag (a coarse...
Performance of analog circuits is highly sensitive to layout parasitics. This paper presents an improved algorithm that automatically conducts performance-constrained parasitic-aware retargeting and optimization of analog layouts. In order to meet the desired circuit specification, performance sensitivities with respect to layout parasitics are first determined. Then the algorithm applies sensitivity-based...
Graphs are popularly used to model structural relationships between objects. In many application domains such as social networks, sensor networks and telecommunication, graphs evolve over time. In this paper, we study a new problem of discovering the subgraphs that exhibit significant changes in evolving graphs. This problem is challenging since it is hard to define changing regions that are closely...
In this paper, an innovative scheduling is designed for multi-hop multicast in wireless mesh networks, with utilization of concurrent transmission strategy. Since the performance of a multicast mechanism is constrained in a wireless setting due to the interference among local wireless transmissions, we analyze the interference relationships firstly among the transmissions by introducing a graph transformation...
Due to discontinuity of traffic, traffic distribution strategy in each intermediate node and each flow's state before transmission should be considered in non-full load wireless mesh networks when scheduling. In this paper, an activeness-labelled concurrent transmission method with unselfish traffic distribution is designed to enlarge throughput in non-full load wireless mesh networks. Firstly, the...
