Recent human matting methods typically suffer from two drawbacks: 1) high computation overhead caused by multiple stages, and 2) limited practical application due to the need for auxiliary guidance (e.g., trimap, mask, or background). To address ...

Due to the fact that things may belong to multiple classifications, the traditional community partition algorithm cannot meet increasingly changing demands; the existing overlapping community partition algorithm still requires specific parameters in ...

In the era of information overload, both information consumers and information producers have encountered great challenges: for information consumers, it is very difficult to find information of interest from a large amount of information. The ...

The traditional laser coding has its disadvantages of poor accuracy and stability. In this work, a reference clock source that uses the precision timing function of the Global Positioning System (GPS) as a frequency hopping code is designed. A model of ...

Security enforcement is an enabler for databases to meet mandatory regulatory compliance and privacy requirements. A well-rounded yet efficient security mechanism would make a database product eligible for high profile government contracts and new ...

In database systems that support fine-grained access controls, each user has access rights that determine which tuples are accessible and which are inaccessible. Queries are answered as if the inaccessible tuples are not present in the database. Thus, ...

Congestion pricing is considered to be one of the best ways to alleviate congestion. A bi-level model based on SDUO-DT/RC (Stochastic Dynamic User Optimal- Departure Time/Route Choice) about the dynamic congestion pricing was established in this paper. ...

Access controls are mechanisms to enhance security by protecting data from unauthorized accesses. In contrast to traditional access controls that grant access rights at the granularity of the whole tables or views, fine-grained access controls specify ...

Fine-grained access controls for XML define access privileges at the granularity of individual XML nodes. In this paper, we present a fine-grained access control mechanism for XML data. This mechanism exploits the structural locality of access rights as ...

Numerous authorization models have been proposed in recent years. While some models support either positive or negative authorizations, hybrid models take advantage of both authorizations simultaneously. However, resolving authorization conflicts is ...

Fine-grained access controls for XML define access privileges at the granularity of individual XML nodes. In this paper, we present a fine-grained access control mechanism for XML data. This mechanism exploits the structural locality of access rights as ...

One of the major problems in integrating independently developed applications is the divergence between the data and control-of-processing models assumed by these applications. Research on database integration has focused on establishing and maintaining ...

In this paper, we discuss Babel, a prototype tool for integrating multiple heterogeneous applications, by wrapping them and by specifying the logic of their interoperation in XML.
